The vehicle movement using computational fluid dynamics method

Abstract

Underwater vehicles represent underwater robots able to perform tasks without or with a minimum human intervention. Research and development of this vehicles have growing as a result of excellent characteristics operated in different situation. Before discussing the steady motion of underwater vehicle, it is necessary to examine the hydrometeorological condition founded in respectively area. Interaction between the water surface and the atmosphere determine the development and appearance of hydrodynamic processes. The main current encountered in Black Sea Basin moves in a cyclonic direction to the edge of the continental platform and surrounds the entire basin. Using the data in-situ regarding the influence of marine current for different steps of depths, the underwater vehicle reacts different and have to change his input data to follow the right course. This paper provides an intuitive modeling and simulation approach to obtain a distribution of current influence along the underwater vehicle body. The software SolidWorks and Ansys Fluent are used to realize the vehicle design and the simulation. The Ansys software is a powerful tool used for solving problems involving fluid mechanis. The condition imposed for simulation, was generated and determinate in-situ by Current Meter Model 106.
