    Summary: In this paper we present a distributed approach to real-time, interactive visualisation of CFD data. The distribution of the computational effort over several computers allows to assign the different parts of the calculations to those machines best suited to perform them. We illustrate this approach with Parallel CFView, an interactive computational Field Visualisation System that uses both SIMD and MIMD parallel computers as powerfull computational back-ends in a heterogenous and distributed environment. A limited performance analysis is presented allowing to evaluate the heterogenous and distributed approach. Comparisons are made between the performance of both the SIMD and MIMD implementations and the stand-alone CFView system.

    Summary: Broadband cavitation noise of an onboard propeller with a surface from heavily fouled to freshly polished was measured in a 4:1 range of hydrostatic pressure, at a cavitation number to 37% of its critical value. By means of a carefully designed measuring set free field condition, low background noise, and stationarity of noise samples were ensured. Good scaling of integral high- frequency noise level generated by the 10logP2.2 correction. A modulation analysis method for acoustical diagnosis of weak or moderate propeller cavitation, is presented. The method can be used to suppress scale effects in noise modelling.

    Meeting: Second International Symposium on Propeller and Cavitation
    Summary: Experimental data collected in an onboard measurement are applied to check some of the rules used for scaling the frequency of the maximum of a propeller cavitation noise spectrum. The rules proposed by Blake and Ross prove to be applicable only in incipient, viz. developed cavitation regimes, whereas a new rule in the form of a smooth analytical combination of these two rules is in both classes of regimes in a good agreement with the propeller data and also with the data on rotating rod cavitation noise of Lesunovskii and Khokha. However, the new rule does not comply with some published data. on hydrofoil and model propeller cavitation noise.

    Held: from 10/22/92 to 10/24/92
    Summary: The action of an ideal propeller in a wake field is analyzed. A simpler case is considered in which the influence of wake reflects itself only through a change in propeller loading. A wake fraction can be obtained by simply summing the fractions of frictional and potential wake only if the last are small quantities. Generally a complex formula is proposed. The influence which a surplus of mechanical energy in the frictional wake exercises over ideal propeller efficiency, which in this case is utilizing a part of the ship wake mechanical energy, is analyzed.
    Keywords: Wake fraction, hull propeller interaction, propulsor efficiency.

    Held: from 06/24/92 to 06/25/92
    Summary: An example of near-field cavitation noise measurements of an inboard screw propeller is presented. A carefully optimized measurements set ensured good quality of the results, which describe a rather free acoustic field. The stationarity of noise samples, from an inboard hydrophone, enabled a rather fine parametric analysis. This revealed particularities of the noise dependence on the degree of cavitation development as on the hydrostatic pressure. The influence of the state of the propeller surface on the cavitation noise was also investigated.

    Summary: Advanced scientific visualisation system have to be able to perform computationally expensive mapping operations on huge sets of numerical data in real time. However, the specialised nature of modern highperformance computers together with their limited accessibility has often prohibited their use for existing visualisation systems. In this paper we describe and analyse Parallel CFView. In particular, the Interface Framework developed for communication between the different machines, is examined. A performance analysis is presented that allows to evaluate the heterogenous ond distributed approach. Comparisons are made between the performance of both the SIMD and MIMD implementations and the sequential CFView system.

    Summary: CFView is an interactive visualisation system which allows simultaneous inspection of structured and unstructured fluid flow simulations. It uses data extraction operations such as cutting plane, isosurface and particle trace to uncover interesting features of large numerical data sets. These routines, which often require very large amounts of computational resources, seriously reduce the interactiveness of a visualisation. In this paper we present and analyse Parallel CFView. In particular, the interface framework developed for communications between the different machines, is examined. A performance analysis is presented that allows to evaluate the heterogenous and distributed approach. Comparisons between the performance of both SIMD and MIMD implementations and the sequential CFView system show that speedups of a factor of 10 can be obtained on large data sets.

    Summary: The phenomena occurring during an unstedy flow through a pipeline are reviewed. Two kinds of phenomena are separately investigated: firstly, the phenomena independent of the fluid compressibility, so-called fluid-transients, and secondly, the water hammer, the phenomenon essentially dependent on the sound velocity in a fluid. The essence of the water hammer phenomenon is explained, and the partial differential equation describing it is derived. The computer program intended for solving the technical problem concerning the calculation of the pressure along the pipeline, when the dependence of valve opening or closing on time is given, is described. Particular scenarios of the working conditions of a pipeline are considered and their danger is evaluated.

    Summary: The dissertation presents a method for designing and adjusting technical system's maintenance concept, cost effectively, with preservation of safety limits. The method is applied to merchant vessels. Therefore, an introducion to ship maintenance is presented. The life cycle costs (LCC) approach is central to maintenance considerations. Therefore, ship's life cycle phases, and maintenance aspests in each of these, are discussed. The method: Maintenance Concept Adjustement and Design, or MA-CAD for short, resulted from the research carried out in view of goal 2. This method is the kernel of the thesis. The method is tested in a case study, made for characteristic machinery: ship's main engine. The study included two Nedlloyd vessels, and several maintenance data sources: history data, spotlight registration, data from clasification societies and engine manufactures, and data from other maintenance studies.

    Summary: Ship performance on waves has always been one of the problems in ship design. Today, this problem becomes even more distinct because of modern fast passenger vessels and high- powered cargo ships. However, remarkable advances in oceanography and computer technology made possible to predict many aspects of ship performance at sea. The theory of Salvesen, Tuck and Faltinsen is presented for predicting two-dimensional hydrodynamic reaction and excitation at wave. A computer program based on this theory and with accurate Frankžs close-fit section representation has ben developed, and has been adapted to GIOP computer program for computing ship motion and loads on harmonic waves. That program has also been tested for two simple cross section and two most common ship sections, and for whole S175 ship hull.

    Summary: The J.E. Kerwin's linearised lifting surface theory is employed for modelling the flow past plane wing and screw propeller, with and without end plates. The fluid is assumed to be homogeneous, incompressible and inviscid. Later on the influence of the viscosity is calculated by using approximate plate resistance formula. The two-sided symmetrical end plate is considered, according to J.A. Sparenberg. The theoretical-numerical-computer model enables the calculation of the circulation distribution along span of the plain wing, and radial along the blade of screw propeller, with and without end plate. The lift and drag forces for different angles of attack of plane wing are calculated, and the resultes are given for uniform and nonuniform incoming flow. The numerical open water test was carried out for both screw propeller with and without end plates. The thrust and torque are determined and the open water characteristics are presented.

    Summary: The demands imposed on CFD software have increased greatly in recent years. Applications are becoming more and more sophisticated. The Object Oriented Technology is therefore becoming a significant element for the CFD specialist in the design and implementation of next generation softwares. New concepts of Object Oriented Programming (OOP) introduce the principle of software decompositions in layers of abstractions in order to improve the communications and the team work, for example of CFD and computer specialists.
