Analysis studying for improving cooling tower

Abstract EN

The present investigation includes a detailed study of the proposed equation for counter flow wet cooling tower using Merkel and Poppe models to show the difference and solutions techniques of the proposed models .

A mathematical model has been suggested to construct computer software MATLB R2013 program for simulation of natural draft wet cooling tower for summer (hot and dry) and winter (cold and wet ) weather according to Iraqi weather .

The fill height changed from (0.2 -1.4)m at different water inlet temperature (37 ،40، 45)oC and constant mass flow rate of air .It was found that the range of cooling increases when the fill is high and the cooling range ,relative humidity ,cooling approach ,air temperature change are higher at winter than at summer while the effectiveness and enthalpy change show higher value at summer than winter .

Also the mass flow rate of water changed from(1- 7.5) kg/s with water inlet temperature 45 oC with constant fill height 1.2 m the result obtained show that tower range ، air temperature change ,are higher in winter than at summer where the enthalpy change and effectiveness show higher values at summer than at winter which matches with the other experimental researches.
