| Abstract: | Numerical methods were used to study the effectiveness of superheated steam, humid air and dry air as dehydrating media in turbulent flow for the drying of wedge-shaped specimens. The Couette flow assumption was used to formulate the coupled heat and mass transfer in the turbulent boundary layer. Superheated steam was found to have highest evaporation rates at free stream temperatures above the inversion point. |
