For more in-depth research on the hydrodynamic performance of VVP, the method for the prediction of the unsteady hydrodynamic performance of VVP by fluent is studied in this paper. The simulation model is built and meshed by tetrahedral, hexahedral unstructured hybrid grid. There is a partial encryption for grid near the VVP and the wake field. UDF program is provided to keep the blades move by the...
In order to validate the application of Large eddy simulation in the field of incompressible flow, the author used Large eddy simulation to compute 2-dimensional incompressible flows around an airfoil by software Fluent. In the beginning of computation, the paper prepared five types of mesh in order to check up the LES requiring for mesh. Then the author monitored lift coefficient and drag coefficient...
To analyse a possible way to improve the propulsion performance of ships, the unstructured grid and the Reynolds Average Navier-Stokes equations were used to calculate the performance of a propeller and rudder fitted with additional thrust fins in the viscous flow field. The computational fluid dynamics software FLUENT was used to simulate the thrust and torque coefficient as a function of the advance...
