摘要

对充满双分散多孔介质（BDPM）的平行板通道中的强制对流进行了分析研究。考虑到通道壁的对流边界条件和动量滑移，采用双速双温模型研究了流体相和固体相的流场和温度场。使用同调分析法（HAM）对控制方程进行非尺寸化和求解，以确定两相的速度和温度曲线。研究结果表明，固相的温度增幅明显大于流相。研究还分析了不同参数（包括达西数、比奥特数、滑移参数和布林克曼数）对速度、温度、努塞尔特数和表皮摩擦力的影响。

Effects of Momentum Slip and Convective Boundary Condition on a Forced Convection in a Channel Filled with Bidisperse Porous Medium (BDPM)

An analytical investigation is conducted on Forced Convection in a parallel plate channel filled with a Bidisperse porous medium (BDPM). The flow and temperature fields are studied for both the fluid phase and solid phase using the two-velocity two-temperature model, taking into consideration the convective boundary condition at the channel walls and the momentum slip. The governing equations are non-dimensionalized and solved using the Homotopy Analysis Method (HAM) to determine the velocity and temperature profiles for both phases. The study reveals that the increase in temperature for the solid phase is significantly greater than that of the fluid phase. The effects of different parameters, including the Darcy number, Biot number, slip parameter, and Brinkman number, on the velocity, temperature, Nusselt number, and skin friction are also analyzed.

期刊介绍： The Journal of Porous Media publishes original full-length research articles (and technical notes) in a wide variety of areas related to porous media studies, such as mathematical modeling, numerical and experimental techniques, industrial and environmental heat and mass transfer, conduction, convection, radiation, particle transport and capillary effects, reactive flows, deformable porous media, biomedical applications, and mechanics of the porous substrate. Emphasis will be given to manuscripts that present novel findings pertinent to these areas. The journal will also consider publication of state-of-the-art reviews. Manuscripts applying known methods to previously solved problems or providing results in the absence of scientific motivation or application will not be accepted. Submitted articles should contribute to the understanding of specific scientific problems or to solution techniques that are useful in applications. Papers that link theory with computational practice to provide insight into the processes are welcome.
