摘　　要：以某企业热风循环茯茶烘房为研究对象,应用数值模拟方法研究送风速度、角度和茶砖间距三种单因素变量对烘房的影响规律,结果表明:适当增加送风速度有利于室内空气流动顺畅,并改善温度场的均匀性;送风角度向下偏转有利于提高流场均匀性;缩短茶砖摆放间距,可减少烘房左侧茯茶温度的不均匀。Taking an enterprise brick tea drying chamber as the object,using numerical simulation method,the influence of 3 factors,flow velocity,flow angle and brick spacing on the drying chamber was investigated,and found that： increased flow velocity can significantly make the air flows more smoothly,and can slightly improve the uniformity of the temperature field in the drying chamber as well; downward deflection angle will help improve the velocity field uniformity; shorten brick spacing can reduce the uneven temperature drying chamber on the left.
