| 摘 要： | This authors uses a physical model of the rectangular channel with dimpled surface to simulate the flow and heat transfer situation. On the basis of actual flow and heat transfer in the channel, it made the interrelated hypothesizes and built up the math model. They adopted the turbulent model, appliy the algorithm to resolve the pressure-velocity coupling and use the experimental data model to check up the feasibility of the model. By the study, the thesis shows the principle of the flow and heat transfer in narrow channel with a dimple surface and gets the factors and the conditions that affect the flow and heat transfer. The results show that the geometry structure and rank distributing of dimple affect the capability of heat transfer evidently. When Reynolds number is low, the capability of heat transfer becomes better as the number increases, and when Reynolds number is bigger than a critical point, there is a little influence.
