| Abstract: | A theoretical model for the porous layer of sintered porous surface tubing（SPST） was established to simulate the flow boiling performances of cooling water in SPST and smooth tube based on Fluent software;and the cloud figures of gas volume distribution and pressure were got under different fluid velocities,including analysis of the velocity and the temperature by field synergy principle.The results show that SPST can enhance the heat flux and influence the pressure drop not too much.Analyzing different pipe flow influences on the vaporization proves the smaller the pipe flow,the greater the vaporization. |
