Abstract

Density profiles of potassium (K) were measured experimentally in a boundary layer on a cooled metal flat plate, and the K density was found to be higher than the estimated value without chemical reactions. Results of the boundary layer simulation with reactions and transport of chemical species showed that this enrichment of the K density was caused when the chemical species densities largely deviated from their thermochemical equilibrium values. The simulation also showed that this phenomenon might appear in a viscous sublayer in a turbulent boundary layer of an actual MHD power generation channel.
