| Abstract: | The natural convective heat transfer model on the air side of air-heating cryogenic finned-tube vaporizer was established.The natural convection heat transfer of vaporizer side air was simulated 3D-numerically used by fluent software,SST model and SIMPLEC algorithm for different structure parameters and inside wall temperature of the vaporizer.Based on the result of numerical simulation,the influence of different structure sizes and wall temperatures on natural convection heat transfer was analysed,and a ca... |
