Bhuiyan et al. [11] caried out three-dimensional CFD simulations to investigate heat transfer and fluid flow characteristics of a four-row plain fin-and-tube heat exchanger using the Commercial Computational Fluid Dynamics Code ANSYS CFX 12.0.
Reasonable agreement was found between the simulations and experimental data.
The results were compared with a CFD model that assumed the heat pipes were solid rods with a constant conductivity.
Numerical simulation results indicate that an optimal perforation design can be obtained to realize a maximum increase in the j factor.

By comparing the calculated results of numerical simulation and semi-empirical theoretical equation, the numerical simulation is proved feasible in oil film state analysis parameter prediction, which can overcome the deficiency of single model and get good effect.
Numerical Simulation Model of the Single Oil Pad.
Three-dimensional geometry model of the oil film is produced by software UG, then the model is introduced into the pre-processor ICEM CFD to generate grid.

So far Computational Fluid Dynamics (CFD) has focused on grid‐based methods, where two different frames are usually considered for describing the physical governing equations, namely: the Eulerian and the Lagrangian description (Table 1).
The development of mesh free methods offers a reliable approach to tackle the simulation of such difficult problems.
In numeric simulation, larger resolution will help reduce errors, which are inevitable in floating point calculation; larger problem domain often means more analogy with realistic experiment and better simulation result.
For this reason, numerical simulation about tsunami wave from submarine slide are very necessary.
