| 摘 要： | 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。 |

| Abstract: | The viscous dissipation effect on forced convection in a porous saturated circular tube with an isoflux wall is investigated on the basis of the Brinkman flow model. For the thermally developing region, a numerical study was reported while a perturbation analysis was presented to find expressions for the temperature profile and the Nusselt number for the fully developed region. The fully developed Nusselt number found by numerical solution for the developing region was compared with that of asymptotic analysis and a good degree of agreement is observed. |
| Keywords: | forced convection viscous dissipation Brinkman model Darcy number Nusselt number |
