Presently the most wave slamming simulation research focuses on the impact pressure and less on the flow field surrounding structures.
The comparison indicates that the regular simulation models can work well to study the process of wave impact.

This present CFD package applies the finite volume method to covert the governing partial differential equations into a system of discrete algebraic equations by discretizing the computational domain into grid mesh.
For a transient simulation, an initial condition is also required to numerically close the equations.
Since the overall error CFD computational is mainly a combination of grid density and convergence criteria.
For this purpose, before verifying our CFD numerical results first we perform a grid study case.

In these simulations we included parameters which are usually neglected in other "straight" numerical methods [11, 12].
Complex FVM simulations (FLUE)T of Ansys Inc.).
This is true as long as sufficiently precise thermal and rheological parameters are included in the simulation.

In the numerical simulation of torque converter, the amount of heat exchange is smaller for the working medium is incompressible steady viscous fluid, so the control equation contains continuity equation and momentum conservation equation.

Thermal Flow Simulation
The schematic drawing of vertical type twin-roll casting process is shown in Fig. 1.
Based on the assumptions steady-state simulations were performed.
The above simulation results show that the temperature distribution was non-uniform because of fixed dams and the different heat flux along roll width.
Experiments and simulation of thermal flow and solidification has verified the casting conditions and strip quality.

The time-averaged thrust coefficient and the propulsive efficiency are evaluated using CFD techniques.
The commercial CFD package, FLUENT 6.3.26, is employed with assuming incompressible laminar flow.
The method is attractive because it produces high-order response information and is computationally cheap compared to techniques with similar capabilities, such as Monte Carlo Simulations (MCS).
