空调室内机导流板角度对流场影响的大涡模拟
Large Eddy Simulation of the Influence of the Angle of Guide Plate on the Indoor Air-conditioner
摘要
Abstract
A two-dimensional model of the whole flow field of indoor air-conditioner was established. Flow field with three different angles of guide plate and three different impeller rotational speed was investigated by large eddy simulation(LES). Calculation results show that the existence of the guide plate can change the direction of fluid flow and the velocity axis region of dispersed jet, which make the indoor flow field and temperature field more uniform. If the angle of guide plate is not suitable, the airflow will be hindered, and vortex shedding at the end of guide plate will be enhanced.关键词
