| Abstract: | It is a complex process with convection heat transfer of multiphase flow and single phase flow,solid conduction and interaction of different flows to cool the gas-particle two-phase flow in a spray granulating tower by jackets.The numerical method of coupled heat transfer between gas-particle two-phase flow and jackets were used to simulate the above process and the temperature distribution in the tower was obtained.The effects of total amount of cooling water(Q),cooling water temperature at inlet(T_(in)) a... |
