A NUMERICAL STUDY ON THE TEMPERATURE FIELD OF LIQUID HYDROGEN ZERO BOIL-OFF STORAGE TANK WITH INJECTION NOZZLES

For liquid hydrogen ZBO storage tank with injection nozzles to establish a two-dimensional axisymmetric CFD model,this model numerical prediction of the temperature field of the storage tank on the temperature field distribution and injection equipment size parameters.The results show that: the best position of the nozzle should be located in the middle of the tank,so as to better reduce the maximum temperature of the liquid to reduce the internal evaporation;the span of nozzle increases,the total opening area of the nozzle increases,but the jet the speed will be reduced,will result in maximum temperature and average temperature slightly increased span length should be set in a certain range.
