All simulations were conducted based on the general-purpose CFD code FLUENT 13.0®, which adopts a control volume based finite difference method to solve the conservation equations for mass and momentum.
Large eddy simulation method was employed in this work.
In the case of r=30, the simulation under predicted the spread width in the zone of large spread zone of w/d>2.00.
And in the case of r=60, the simulation over predicted the spread width in the zone of large spread zone of w/d>2.00.

Numerical simulation of MHD rectangular duct flow with FCI based on magnetic induction method Tianneng Xu1, a, Jie Mao1, b, Huachen Pan1, c 1HANGZHOU ZHEJIANG 310018, HANGZHOU DIANZI UNIVERSITY axutianneng@163.com, bmaojie@gmail.com, chuachen_pan@yahoo.com Keywords: MHD effect; Magnetohydrodynamic; FCI; rectangular duct flow.
The report of case with PEH is rarely seen since it probably requires a full 3D simulation to describe the flow velocity and electric current distributions around each hole.
In this paper, a commercial computational fluid dynamic (CFD) software FLUENT is used to simulate the MHD problem.
Numerical Simulation The structural material of rectangular duct is stainless steel, whose electrical conductivity is σw = 1.4×106 S/m.
Several velocity and pressure diagrams were obtained from the numerical simulation results of case1 and case2.

The internal flow of jet fan has been simulated using FLUENT software.By changing the length of exit duct and the angle of the exit cowl,a series of numerical simulation research has been done.The calculation results show that the length of exit duct and structure of exit cowl has obvious influence on jet fan aerodynamics performances and reasonable export structure can effectively improve jet fan aerodynamic performances.
In order to find jet fan outlet structure reasonable parameters and range of options, numerical simulation research has been done by changing the length of exit duct and the angle of the exit cowl.
Fig.3 is the relationship between flow rate Q and L/D, and data Q are export from the numerical simulation results.
Conclusion The internal flow of jet fan has been simulated using CFD technology.
