Accord ing to the research on comp lex flow prob lem, CFD can reflect flow of flow field exactly. E In th is paper, steady num erical simu lation on flow field in jacketed ice- temperature storagew as done by CFD, the d istribution A n situation of flow field w as analyzed, and the influence of flow field uniform ity w as also discussed in the cond ition of d ifferent air c C . supp ly speed. Its found that jacketed ice- tem perature storage has un iform d istribu tion of flow field; it uses air d istribution m ode g r w ith top static pressure air supp ly and bottom air return then can form top- down un iform piston flow, different air supp ly speed
