| Abstract: | The paper analyzed conductive heat transfer through silicon carbide heat exchanger tube and the effects of the porosity existing in the tube on heat conduction,and discussed also the theoretical calculations of heat conductance of porous Sic ceramic tube.It was found that the porous Sic ceramics has good properties as high temperature heat transfer eleme- nts.The heat transfer enhancement tests with three different kinds of tubulators shown that tube side heat transfer augmentation is effective for enhancing overall heat transfer coefficient K,and the jet enhancement among three tubulalors is the most effective. |
