数值求解了当血管内腔变为多孔结构时，血液在血管中非定常磁流体动力学（MHD）流动的传热传质问题。考虑了渗透率随时间的变化和抽吸速度的振荡。计算结果以图形方式给出了不同表面摩擦系数、努塞尔数和舍伍德数的速度、温度和浓度场。研究表明，流动是明显的磁场的存在下，也由Grashof数的值的影响。
A problem motivated by the investigation of the heat and mass transfer in the unsteady magnetohydrodynamic (MHD) flow of blood through a vessel is solved numerically when the lumen of the vessel has turned into the porous structure. The time-dependent permeability and the oscillatory suction velocity are considered. The computational results are presented graphically for the velocity, the temperature, and the concentration fields for various values of skin friction coefficients, Nusselt numbers, and Sherwood numbers. The study reveals that the flow is appreciably influenced by the presence of a magnetic field and also by the value of the Grashof number.
