Abstract

In this paper, we study the hydrothermal characteristics of flow inside a rotating helical pipe filled with a saturated homogenous porous medium. The analysis is being carried out for the case of small curvature and torsion. Using perturbation approach, velocity and temperature fields are solved for both uniform wall heat-flux and uniform wall temperature boundary conditions. Perturbation expansion up to third-order is carried out to investigate the effect of rotation on the flow. The influence of rotation on velocity is noticed as early as the first order, and on temperature solution, it has an effect in the third order. The influence of rotation on Nusselt number does not appear till third order, and it is discovered that Nusselt number grows as dimensionless curvature increases.

充满饱和多孔介质的旋转螺旋管内的对流传热

本文研究了充满饱和均质多孔介质的旋转螺旋管内流动的水热特性。分析针对的是小曲率和小扭转情况。采用扰动方法，求解了均匀壁面热流和均匀壁面温度边界条件下的速度场和温度场。为了研究旋转对流动的影响，进行了高达三阶的扰动扩展。旋转对速度的影响最早出现在一阶，而对温度求解的影响则出现在三阶。旋转对努塞尔特数的影响直到三阶才出现，并且发现努塞尔特数随着无量纲曲率的增加而增加。
