采用长波长和低雷诺数近似方法研究了壁面滑移条件、多孔介质和传热对含悬浮颗粒的MHD牛顿流体在导管内蠕动流入的影响。导出了速度和温度的解析解。用振幅比、颗粒浓度、导管尺寸和无量纲流速等参数来讨论压力梯度。对分析中得到的速度解和温度解进行了数值计算和研究。管表面保持在固定温度下。讨论了物理变量随相关参数的变化情况。所建立的数学模型对应于两个同心管之间的环形空间内的流动。推导出热能量随粒子浓度的增大而减小，并在滑移条件下通过导管。在壁面磁场和滑移条件下，流动加速，在导管处流动减小。导管尺寸对压降和摩擦力有不同的影响。
The effect of wall slip conditions, porous media, and heat transfer on peristaltic inflow of MHD Newtonian fluid with suspended particles in a catheterized tube has been studied with long-wavelength and low-Reynolds number approximations. The analytical solution has been derived for velocity and temperature. The amplitude ratio, particle concentration, catheter size, and the dimensionless flow rate were used to discuss the pressure gradient. The solutions for velocity and temperature derived in the analysis have been computed numerically and investigated. The tube surface is maintained at a fixed temperature. The variations of physical variables with the pertinent parameters were discussed graphically. The mathematical model presented corresponds to the flow in the annular space between two concentric tubes. It has been deduced that the thermal energy is reduced with particles' concentration and with slip condition through the catheterized tube. The flow accelerates with the magnetic field and slip condition at the wall, whereas it decreases at the catheter. The catheter size has a different effect on both pressure drop and friction force.
