1求解粘性流体和热迁移联立方程的迎风局部微分求积法显示文摘 微分求积方法(DQM)已成功地应用于数值求解流体力学中的许多问题· 但是已有的工作大多限于正规区域的流动问题,同时缺少用迎风机制来描述流体流动的对流特性· 该文对一个不规则区域中的不可压缩层流和热迁移的耦合问题给出了一种具有迎风机制的局部微分求积方法,对通过边界和坐标不平行的收缩管道中的流体,只用少数网格点得到了比较好的数值解· 和有限差分方法(FDM)相比较,这一方法具有计算工作量少。A.S.J.阿尔赛夫 朱正佑 2004应用数学和力学2004,25,10:6
2NUMERICAL SIMULATION OF FLOWS FOR SECOND-ORDER VISCOELASTIC FLUID COUPLED WITH HEAT TRANSFER BY DIFFERENTIAL QUADRATURE METHOD显示文摘The problem of two-dimensional steady flow of an incompressible second-order viscoelastic fluid coupled with heat transfer between parallel plates was considered. A viscous dissipation function was included in the energy equation. When the elastic property of the fluid is weaker, the zeroth-order and first-order approximate governing equations were obtained by means of the perturbation method. To understand the behavior of flow near the tube wall, the half-domain was divided into two sub-domains, in which one is a thin layer near the wall called the inner domain and the remainder is called the outer domain. The governing equations in the inner domain and in the outer domain were discretized respectively by using the Differential Quadrature Method (DQM). The matching conditions at the interface between the inner and outer domains were presented. An iterative method for solving these discretized equations was given in this paper. The numerical results obtained agree with existing results.AL-SAIF A.S.J. 2005Journal of Hydrodynamics2005,17,2:2
