分析粘性、不可压缩、互不相溶流体,在竖直的波状壁面和光滑的平面壁间,传热传质混合对流的组合效应.得到无量纲控制方程的摄动解:0阶的均值部分和1阶的摄动部分.将所得到的1阶量,用小波长摄动级数展开,出现按指数阶分类的方程组.得到了0阶和1阶的解析表达式及其整体解,通过数值计算,用图形表明流体流动的显著特征以及传热特性.界面上应用适当的匹配条件,使分离的解相匹配.还针对控制参数的不同变化,分析了剪应力和Nusselt数的变化.发现Grashof数、粘性比、宽度比和导电率,对平行于流动方向的速度是有利的,对垂直于流动方向速度的影响正相反.
The combined effects of heat and mass transfer mixed convection are analyzed for viscous, incompressible, immiscible fluids, and between vertically wavy and smooth planar walls. The perturbed solution to the dimensionless governing equation is obtained: the mean of the 0th order And the perturbation of order 1. The first-order quantities obtained are expanded by small-wavelength perturbation series and the exponential order equations appear.The analytic expressions of 0-order and 1-order and their general solutions are obtained, By numerical calculation, the fluid flow characteristics and heat transfer characteristics are graphically illustrated, and the appropriate matching conditions are applied on the interface to match the dissociation solutions. The changes of shear stress and Nusselt number are also analyzed for different changes of control parameters. The Grashof number, viscosity ratio, width ratio and conductivity were found to be favorable for the velocity parallel to the flow direction and the opposite for the velocity perpendicular to the flow direction.
