AbstractThis article obtains the viscous force and added mass for a complex configuration. its subject is a small AUV propelled by four pumps at stem, which is used to survey the ocean. The model in simulation is similar to actual body without any simplification in order to get high resolution result, with Meshing by unstructured grids based on advancing front method. The steady viscous force is calculated by integrating RANS equation by cell centered finite volume scheme, and compared with that of experiment. The simulation data is within 1.7 percent with respect to that of experiment. Motivated by this, we apply this method to calculate the unsteady force of AUV. In order to achieve high resolution for unsteady viscous flow, an implicit dual time approach, which is proved to be more stable, is applied to discretize the time-dependent conserved variables. Applying this method to the complex pump-propelled AUV unsteady motion, its resistant force and corresponding velocity are obtained at each time step. With curve fitting method, we acquire the added mass. At the same time, the experiment data of max velocity, total time and total displacement are got as ALTV slips from max velocity without thrust, which agrees well with that of simulation. The emphasis of the paper is placed on the practicality of the methodology for accurately predicting viscous drag data and added mass for complex configuration.
