Investigation of heat mass transfer processes in the boundary layer with injection

Perepechko L.

2000

Vol. 21, nr 3-4

41-54

The heat mass transfer processes were studied in a boundary layer over the porous flat plate using the two-parameter turbulence model. The flows with evaporation of ethyl alcohol, and water and also flows with injection of hydrogen (helium) into the laminar and turbulent outer air flow were calculated. Similarity of heat and mass transfer processes and the effect of diffusion component of the heat flux on calculations of the flow field were investigated. Comparison with experimental data on distribution of the average characteristics in the boundary layer is shown.
