| The free dissolution behavior of nickel in aluminum is studied in the temperature range 750-900$spcirc$C using a combined experimental and numerical technique. This combined approach determines that mass transfer is solely diffusion controlled through the boundary layer, and the mass transfer coefficient follows an Arrhenius relationship with temperature. Exothermicity increases mass transfer by increasing liquid solubility at the moving boundary. Theoretically derived correlations for Sherwood and Nusselt numbers employing modified Grashof numbers are supported by experimental and numerical evidences. |
