摘要
旨在研究空调送风参数对室内热流场的影响,以某9m旅行客车为研究对象,建立三维流场模型;基于RNG k-ε湍流模型;采用SIMPLE算法计算了客车室内5组不同送风参数下的气固耦合传热问题。结果表明:送风角度对整体温度场与速度场的分布影响较大,送风角度为15°时乘员舒适性较好;在送风温度不变的情况下,随着送风速度的增加室内平均速度增大,车内平均温度也随之降低,而送风温度仅对温度场有明显影响。
The study aims to investigate the effect of inlet air parameters on indoor heat flow field. Geometrical model was built based on a 9m coach. The influences of five groups of different air parameters on the interior velocity and temperature filed were calculated using RNG k-ε turbulent model and SIMPLE algorithm. The results manifest that inlet air angle has a great effect on the velocity field and temperature field, passenger＇s thermal comfort is well when the inlet air angle is 15 degree; with the increasing of inlet air velocity, the interior average temperature is reduced; the inlet air temperature only has an influence on temperature field.
