s:The physical and mathematical model of a rotary solid desiccant dehumidifier have been developed.in which the transient air humidity and temperature terms have been taken into consideration. By using one-order upwind differencing scheme and fully implicit scheme, a computer program fgr the rotary dehumidifier──RDEH has been compiled.The comparison between RDEH and other codes programmed by other authors shows that the computation model and computation method are correct and RDEH can be used in more cases such...

s:The physical and mathematical model of a rotary solid desiccant dehumidifier have been developed.in which the transient air humidity and temperature terms have been taken into consideration. By using one-order upwind differencing scheme and fully implicit scheme, a computer program fgr the rotary dehumidifier──RDEH has been compiled.The comparison between RDEH and other codes programmed by other authors shows that the computation model and computation method are correct and RDEH can be used in more cases such as stationary or rotary. steady or unsteady states and the results are more resonable for its more comprehensive nature. Considering the circumfurencial convection is the most important feature for RDEH.

建立了转轮式干燥剂除湿器的物理模型和数学模型,在控制方程中增加了周向对流项和及非定常项和。编制了RDEH程序,程序采用松弛迭代法求解控制方程,空间差分采用一阶迎风格式,时间差分则可根据需要采用显格式、全隐格式或其它半隐格式。将RDEH与国外非转动及转动式除湿器的数值计算结果作了对比,表明建立的模型及计算方法是正确的,且精度高,适用范围广。
