Simulation Calculation and Design Optimization of Shelter Duct
The improved design of shelter air conditioning duct can improve the uniformity of air output.In this paper,a simulation model of a command center's sheltered air duct is established,and the flow field inside the duct is simulated and analyzed.Combined with the simulation results and empirical design,the round-corner transition optimization is applied to the abrupt change of the air duct section.The simulation results show that the return area at the bend of the optimized air duct basically disappears,the uniformity of the flow field in the air duct is improved,the uniformity of the air duct outlet is obviously improved,and the comfort of the shelter is improved.
