Numerical Simulation of Airflow Organization in Air-conditioned Room with Different Air Supply Velocities

以办公室空调房间为研究对象,运用计算流体力学(CFD)中Fluent软件数值模拟,对不同送风速度下空调房间的速度场、温度场进行三维数值模拟,对比分析不同送风速度对气流组织的影响。通过对几种不同工况下不同空间位置的速度云图、温度等值线图的分析,得到了不同送风速度对房间气流组织及热舒适性的影响。

Taking an air- conditioning room as the research object, using the numerical simulationsoftware Fluent of Computational Fluid Dynamics （CFD） , according to the result of three dimensionalnumerical simulation of the velocity field and temperature field of the room under the condition of threedifferent air supply velocities, the influence of airflow field under different velocities is analyzed. Based onthe analysis of the velocity contour map and temperature contour map of different space position underdifferent conditions, the conclusion shows the influence of different air supply velocities to airflow field andthermal comfort.
