基于Brinkman流动模型,研究了等通量壁多孔饱和圆管中粘性耗散对强迫对流的影响.在热发展区域,进行了数值研究;在充分发展区域,进行了摄动分析并求得温度分布的表达式和Nusselt数.在发展区域,利用数值解得到的充分发展Nusselt数与渐近分析结果进行了比较,吻合很好. Based on the Brinkman flow model, the effect of viscous dissipation on forced convection in porous saturated tubes with isotropic wall was studied. In the hot area, numerical studies were carried out. In the fully developed area, the perturbation analysis was carried out and the temperature distribution And the Nusselt number.In the development area, the fully developed Nusselt number obtained by numerical solution is compared with the result of asymptotic analysis, which is in good agreement.
