Abstract
Field tests and numerical calculations are described on the thermal characteristics of the cross flow heating towers using ethylene glycol solutions. continued from Part I for counterflow towers. First, a simple correlation factor method of crossflow calculation is proposed. Next, the data on the overall enthalpy-transfer coefficient. Ka. in a crossflow heating tower are presented and compared with those in a cooling tower of the same type. From the numerical calculations and discussions. diagrams and a simple relation are obtained useful for the design and performance tests of heating towers. The diagrams are expressed in terms of the number of transfer unit. flow ratio. AL. And AG as dimensionless parameters. The variation of thermal performace of heating towers may be expressed by the relation that AL= const.
