System Research in Energy| Summary: | We have developed a method for calculating the degree of liquid cooling in film cooling towers with a profiled sprinkler surface under the conditions of quiescent air and intense blowing about the water film. The method is based on our experimental investigations that result in finding a highly efficient heat-exchange surface with spherical dimples that can be recommended as sprinklers for cooling towers.We have analyzed a series of factors that affect heat transfer from water to air on the recommended profiled surface. Some calculations of the degree of water cooling in a cooling tower with air flow transverse to the film have been performed by the developed method. It has been shown that the same degree of cooling can be obtained in the recommended cooling tower in different ways: for example, by varying liquid flow rate and air-flow velocity, or sprinkler length and air velocity. This extends the possibilities of maneuvering modal and constructive-technological parameters of cooling tower depending on specified conditions.The method is developed for engineering use. |
