Investigation of evaporation with open water surface in forced convection

  • 1 Budapest University of Technology and Economics, Hungary

Abstract

Numerous publications in the literature deal with the investigation of evaporation under forced convection; however, no correlation between the available equations would describe the process and the evaporation rate with high reliability and in a wide range of interpretation. The main parameters influencing the evaporation rate are air temperature, relative humidity and velocity of air, liquid temperature, and the surface area of the evaporating liquid. The cases of evaporation were categorized as a function of the indicated parameters under forced convection. For the case with constant gas and liquid parameters, a general Sherwood equation was created using the literature results which can be used to estimate the rate of evaporation, the rate of mass transfer. For this, an equivalent characteristic length and the ratio of gas and liquid temperature were determined
