| 摘 要： | 对流扩散问题的求解关键是确定流场,而运动方程中最困难的就是对两个一阶导数项的处理,本文主要是解决另一关键问题——压力梯度项的处理.当利用有限体积法计算流动和传热问题时,普通的网格和离散方法无法检验出不合理的压力场[1],为了克服这一困难,通常采用交错网格技术,即把速度u,v和压力p(包含其它所有标量场和物性参数)分别存在三套不同的网格系统.这可成功地解决压力与速度的耦合关系问题,SIMPLE算法是压力修正算法的主导方法,本文采用的SIMPLEC算法就是SIMPLE的一种改进.

| Abstract: | The key of Convection-dispersion’s solving is to determine the flow field,the most difficult is to process two first-order derivation term.this paper is mainly to solve another crucial question of pressure gradient.When using the finite volume method for calculation of flow and heat transfer problem,ordinary grid and discrete method can not check out the unreasonable pressure field,in order to solve this difficulty,usually staggered-mesh technique was adopted,put the speed u,v and the pressure p in three different sets of gride system.It can solve the pressure and speed of the coupling relationship problems,SIMPLEC algorithm is a improvement of SIMPLE in this paper. |
