CFD Simulation Approach for Semisubmersible Response in Waves Based on Advanced Techniques Ionuț Cristian SCURTU “Mircea cel Batran” Naval Academy, Constanta, Romania ionut.scurtu@anmb.ro Keywords: Semisubmersible, Response function in waves, CFD software, UDF functions Abstract.
Simulations presented are done in CFX and Fluent, Ansys modules, with same initial conditions and same data analysis in CFD-post.
Results from CFX numerical investigation In this step, we use ANSYS CFD-Post to view the results of the three column semisubmersible simulation.
CFX simulation results are opened with CFD-post in order to extract results according to each time step.
Solver solution variation in CFX for torque and force monitor Results from Fluent numerical investigation The Fluent simulation results can be opened for analysis with the same CFD-post in order to easily compare with CFX results.

Fatigue Analysis of Pure Waterjet Nozzle-A CFD and FEA Approach Quanchang Li1, a, Kai He1, b and R.
The results obtained from two simulations (velocity, pressure) show a good agreement with the theoretical predictions, which indicates that the approach based on CFD and FEA is absolutely feasible.
To predict the nozzle failure, a simulation approach based on CFD and FEA is adopted to analyze fatigue failure of pure waterjet nozzle and the first failure point inside nozzle is found out.
In addition, the turbulence model was used in the CFD.
The whole simulation process was shown in Fig. 1.

The Simulation and Optimization on Flow Field in Intake Port of Engine Based on RE and CFD Dan HAN1, Qian WANG1 ,Binghuan Li1,Guojun ZHANG2,Shuo WANG2 1School of Energy Resources and Power Engineering, Jiangsu University, Zhenjiang 212013,China 2Research Center of Fluid Machinery and Engineering, Jiangsu University, Zhenjiang 212013 qwang@ujs.edu.cn Keywords: Gasoline engine, Intake port, CFD numerical simulation, Discharge coefficient.
In this paper, three-dimensional CFD calculation and structural optimization were used to research the performance of gasoline engine.
The results of the simulation of flow field characteristics analysis show that the simulation and experimental results are in good agreement.
As can be seen from fig.7, the discharge coefficient obtained by simulation and experiment are consistent, but the discharge coefficient obtained by simulation is slightly less than the experiment.
CFD simulation results were analyzed to evaluate the intake system, and an improved scheme is put forward.

A simplification method is used during the simulation process to solve the difficulty of model building during the simulation of the mist pad.
After CFD simulation, model experiment study is carried on using a small scale wind-tunnel.
The pressure drop is gained to testify the numerical simulation result.
Abbaspour etc used CFD method to predict pressure drop of mesh mist eliminator with a large number of mesh grid more than 100,000,000[1].It is good to insists that CFD simulation for demister pad causes difficulty because of tiny diameter of wire mesh and it is so hard to simulate because of limitation of computing and in some cases complex structure of wire meshes.

CFD Simulation of Gas-solid flow in Dense Phase Bypass Pneumatic Conveying using the Euler-Euler Model Y.
The simulation was conducted using the commercial Computational Fluid Dynamic (CFD) software Fluent with the Euler- Euler model accounting for four-way coupling.
The results indicate that pressure prediction of the CFD simulation model for a bypass pipe is promising.
The Euler-Euler model was employed in the CFD simulation to predict gas-solid flow pressure in the bypass pipeline.
This research and simulation work is the initial step in CFD modelling of bypass pneumatic conveying.

In the past decades, little research was carried on about the APR, especially the simulation studies.
In the present simulation, the shear-stress transport (SST) - turbulence model is usually adopted as the turbulence model.
Calculations with different mesh distributions and quantities are carried out to demonstrate that the simulation results are grid independent.
Another reason is that, as known to all, there exists variance in the CFD simulation.
A few conclusions can be drawn based on the simulation results and shown as follows: 1.
