Abstract
Years of field observation has shown that,many cooling towers′ fan flowrate can′t reach the design value.This problem might be caused by the following two0reasmns: one is the design defects of the fan,and the other is the inaccurate calculation of the aerodynamic characteristics of the cooling tower.In order to know the aerodynamic characteristics of the cooling tower and its changing regulation,the aerodynamic characteristics of the airflow around air inlet of counterflow mechanical draft cooling tower were studied through physical model experiment,and the formula for its resistance calculation was given.It was demonstrated that,the calculation result of the resistance of the airflow around air inlet using the code formula tended to be inaccurate.The study results can provide reference for the design of cooling tower.
