Numerical and experimental studies were conducted for open type forced draft
water cooling tower. The numerical part includes a three dimensional computational
solution of air and water simultaneous equations which represents the fluid flow,
heat transfer and mass transfer. Finite volume method with staggered grid and ke-
turbulent model was used. Experimentally, mechanical forced draft counter-flow
cooling tower was used to validate the numerical results. The agreement seems
acceptable between the numerical and experimental results.
