|Abstract||This paper describes the possibilities of the OpenFOAM open source CFD package and its adaptation to the problem of analysis of noise characteristics of marine underwater objects (ergatic and robotics complexes) in case of spatial maneuvering. This paper concerns with the technique of working with the freeware CFD package OpenFOAM, which provides a powerful set of tools for hydro- and aerodynamic experiments on modeling the interaction of the environment with the object under investigation. A general approach to this kind of experiments and an exam- ple of its application to the investigation of marine underwater objects (ergatic and robotics com- plexes) noise during spatial maneuvering are considered. This investigation is intended to serve as an success estimation of the developed algorithms for object"s low noise maneuvering and poten- tially to become an alternative to expensive sea trails, wind tunnel tests. To achieve this goal we suggest to use rich capabilities of utilities such as cavitatingFoam, cavitatingDyMFoam, interPhaseChangeFoam coupled with the integration of the OpenFOAM library code with marine underwater object movements control algorithms developed by the authors. Few approaches to this integration are suggested, some of which have already been implemented by team. In the arti- cle attention is also paid to the rich capabilities of open source package ParaView, distributed with the OpenFOAM. It helps with the visualization of the simulation results of fluid flow and the influence of the environment on the subject, which include both the creation of three-dimensional visualization of the experimental results, streams and eddies, and of individual slices views and animations generation. The possibilities of the experiment setup for OpenFOAM to automatically build visualizations with given structure supported by means of FunctionObjects, allowing to carry out post-processing of results during the simulation are considered. The possibilities of parallel and distributed simulation using OpenFOAM, allowing, in cost of the small changes in the settings of the experiment, to significantly reduce the computational load to an individual computers and to reduce the simulation time. For these purposes, OpenFOAM uses the other common open source package OpenMPI.|
