| 基金项目： | Acknowledgment The first author would like to acknowledge the support provided by Persian Gulf University. Note added in proof. We are indebted to M. F. Shen, assistant to editor of the journal of Applied Mathematics and Mechanics （English Edition）, for pointing out to us that the limitations on the Brinkman flow model should be reminded to the reader; as we did in our Introduction. |
| 摘 要： | 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 is reported while a perturbation analysis is 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 is compared with that of asymptotic analysis and a good degree of agreement is observed. |

| 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 is reported while a perturbation analysis is 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 is compared with that of asymptotic analysis and a good degree of agreement is observed. |
