In China, to calculate airflow resistance coefficient of a natural draft cooling tower, the following experimental equation is usedWhere: D is the diameter of a tower ; h is the inlet height ; F is the area at elevation of the packing; F1 is the outlet area; ξf is the resistance coefficient of the drench device.Equation (1) has obvious defects because it contains no influence of water loading, airflow velocity and the herringbone columns etc.In this paper, a new equation for the caluclation of the airflow resistance coefficient of a cooing tower from the inlet to throat has been obtained as following:Where: ε is the rate of the inlet area to the area at elevation of the packing, other symbols are same as above.Equation (2) is used under the condition that there is no water, while equation (3) is used for rain zone. Therefore, the airflow resistance coefficient for a cooling tower from inlet to throat isEquation (4) can be used in normal design conditions.

A two-dimensional diffuser with a lower curved wall and upper flat plate is studied.There is aparallel channel connected with the exit of the diffuser.The turbulent boundary layer separates on thelower wall due to the strong adverse pressure gradient,and then the separated boundary layer reattach-es on the parallel channel.In the inlet of the diffuser,Reynolds number based on the inlet height ofthe channel is 10400 and based on the local boundary-layer momentum thickness is 4980 and the inletvelocity is 2 5.2m/s.A two-dimensional laser doppler velocimeter was employed to survey the flowfield.Mean velocity and Reynolds stresses were measured from upstream of the separation to thedownstream of the reattachment with 23 sections.Theminimum distance from the surfaceis 0.3mm. The wall pressure and static pressure profiles are presented. The result shows that the strong adversepressure gradient ,wall curvature and strcamline curvature play an important role in the separation. The analysis gives that cross-stream pressure gradient is signifieant in the separating flow. The maxi-mum of the displacement thickness curvature K_(max)corresponds to the intermittency transitory detach-ment(ITD)and to the minimum normal pressure difference. Sandborn&Kline′s separation criterion isnot suitable to the present flow due to indicate a smaller separating region than that in the experiment.several velocity profiles are compared with the experiment.Bardina′s velocity profile can fit the ex-perimental results well before ITD,but ean not fit those well in the detached flow,Cross′s velocityprofile can fit the experimental profiles well in the separated flow.

本文应用二维双色四光束激光多普勒测速仪和压强探针详细地测量了二维非对称曲面扩张通道内的不可压湍流边界层分离流动,得到了时均速度和雷诺剪应力以及正反向间歇流动因子和静压分布。实验结果分析表明:湍流边界层分离时,沿边界层高度方向存在着明显的压强差。压强差的极小值对应于位移厚度曲率的极大值和瞬时间歇分离点。Bardina对数尾迹律可以较好地描述瞬时间歇分离点之前的边界层速度分布,但无法描述分离的边界层速度分布。
