Results of the simulation reveals that velocity has little effect on the flow field distribution.
In this research, with different inlet flow, the flow characteristics in cooling water jacket will be analysed based on CFD method for a better understanding of the effect mechanism for the cooling performance.
Results and discussions Based on the factors influencing the flow field, different conditions was adopted in the numerical simulation of internal flow in the engine cooling water jacket.
Two inlets were set in the simulations with one in the same side of the outlet and with the other in the opposite.

The zone for the calculation of CFD is confined to the surrounding of the airfoil, whilst the free vortex model accounts for the far field of the airfoil.
Methods for computing airfoil aerodynamic characteristics range from coupled potential flow / boundary layer to fully blown computational fluid dynamics (CFD) calculations of the Navier-Stokes’ equations.

Our design was then analysed by using computerised fluid dynamic (CFD) simulation software called STAR-CCM+ which is widely used in automotive simulation.
Based on simulation, we can see that the velocity and pressure profile is distributed differently on entire body.
Simulation of chasis strength was done by using SimDesigner V5R14.
First, based on CFD simulation shown, we manage to get a desirable result in terms of aerodynamic characteristics with Cd = 0.31.
Second, using SIMDesigner simulation on chassis strength, we get maximum bending strength 179 MPa with maximum displacement of 0.3088 mm.

But at present, the Fluent software was rarely used in the simulation of industrial crystallization, especially for 3D simulation of gypsum crystallizer[10-14].
Wei et al [17] solved the population balance equation for crystallization process related to the basic equations of fluid mechanics in an actual mold CFD study for the first time.
But the research was confined in the small size of a simple mold, and only a single-phase simulation was taken instead of multiphase simulation of the mold.
Computational fluid dynamics( CFD) simulations were performed under 100 r/ min for a developed industrial continuous crystallizer.
Therefore, the 3D simulation model of gypsum crystallizer based on CFD can be used to optimize the industrial crystallizer.

This paper presents a simulation of falling behavior for a torpedo anchor using a CFD model and analyzes the effects of hydrodynamic parameters to the directional stability of the free-fall anchor.
Naming the model as H4.36 (named using ‘H’ and ‘x value’), the 300m height falling procedure of the model, from 2700 to 3000 m undersea, can be simulated by using a CFD software.
Table 1 summaries the simulation results of the above three models.

Therefore, we planned to design a novel rotor-type micromixer and to explore the mixing flow mechanism with CFD method.
One complete cycle of rotor motion was performed with 1080 time steps and the iteration number for each time step is 200 to ensure the convergence of simulations.
We intended to multiple the original number into two and four times then conducted the CFD runs.
For improvement the simulation efficiency, further CFD runs were conducted with the 2x density grid system which represented the grid number was 10710.
The present work employed CFD model and dynamic mesh technology to test a variety of operating conditions on the mixing efficiency.

The obtained contours were results obtained by the simulation in fluent and the values of mach number at the exit obtained through computational simulation was found to be close to the theoretical values and the small discrepancy in values of simulation for the viscous flows can be explained by the isentropic assumptions involved in the theoretical values.

This air ventilation rate was necessary to supply to occupant to experimental classroom and also as input value to CFD simulations.
The first idea was application the lowest possible air ventilation rate like value input for next real experimental measurements and also like value input to CFD simulations.
This air ventilation rate was necessary to supply to occupant to experimental classroom and also as input value to CFD simulations.
These values ​​were used and reflected in the experimental measurements and CFD simulations.
