Abstract:
The problem of mass transfer by sublimation from a snow surface subjected to radiation and forced convection is investigated. The effect of irradiation from a nonisothermal source on the mass transfer rate is studied. Forced convection of the flat plate and entrance region type is investigated. Entrance effects are seen to have a negligible influence on the mass transfer rate. The effect of the nonisothermal snow surface is shown to be negligible. A thermal network analysis is developed to predict the mass transfer rate due to the combined effects of radiation and forced convection. Experimental results for mass transfer from a snow surface in the entrance region of a rectangular duct show good agreement with the predicted mass transfer rate. Author
