Numerical Simulation on Thermally Driven Heat Transfer in Several Small-Size Circular Channels in Gravitation Field

Abstract:

In this paper, numerical simulation was performed to comparatively research the thermally driven heat transfer phenomenon of the four kinds of small-size circular channels in the gravitational field. Four kinds of the channels were headed at one end and cooled at the other. At the same time, the thermal drive of fluid was used to accomplish the heat transfer in a high body-force field. The research results indicate that four kinds of circular channels have the same thermally driven heat transfer rule. Furthermore, the thermally driven heat transfer power can be enhanced with the addition of the circular channels. Therefore, when we utilize micro-cyclic channels to cool turbo-vanes, the adoption of multi-cyclic channel may be a feasible design because the adaptability of fluid can be utilized to enhance the heat transfer.
