Bionic Optimization of Heat Conduction with Phase Change under Constant Heat Flux

To enhance the cold release from phase change material (PCM) under the condition of microgravity,the iea of bionic optimization and the Finite Element Method have been taken to study the optimum arrangement scheme of high conuctivity material (HCM).Results show that with time intergration of thermal graient as criterion to determine where to locate HCM the application of the idea of bionic optimization can be extended from the steady heat conuction problem to the unsteay one with phase change.Compared with the method of man-made arrangement schemes,the arrangement of HCM gained by the method of bionic optimization can obviously enhancethe cold release and lower the temperature rise at the entrance of heat flux,an the bionic metho can also overcome its isavantage of large work and the un-complete problem that the schemes obtained by the metho of man-made arrangment scheme may not include the optimum one.
