Flow Investigations have been carried out using CFD Code``FLUENT'' which is based on cell centered finite volumeapproach.Second order discretization scheme was used for all governing equations since the grid which consists of tetrahedral cells are usually not collinear to the flow direction.Under relaxation factor has been used for all parameters to satisfy Scarborough condition for convergence.Coupling between the pressure and velocity field was established using PISO scheme which is based on the higher degree of the approximate relation between the corrections for pressure and velocity as it is more appropriate for swirling flows.All discretized equations have been
solved using segregated solver.An implicit solution scheme with conjunction of Algebraic Multigrid (AMG) has been used for faster convergence.Double precision was used in the computation and solutions were converged until the sum of the all the residual terms was less than 106.

水平有限,不准确,凑合看吧.
FLUENT作为计算流体力学(CFD)程序,适用基于单元中心的有限体积法来进行流动分析.对于通常来说与流动不同向的四面体网格,采用空间二阶精度的差分格式.各参数在松弛因子的作用下通常能够满足流场收敛的Scarborough条件.通过PISO格式,将压力和速度场耦合,模拟二者之间的关系,更适用于有旋流动.所有差分方程使用分离求解器,时间上的隐式格式联合代数多重网格方法用来提高收敛速度.计算中和求解中可以使用双精度,直到残差降至10e-6的级别.
