TURBULENT BOUNDARY LAYERS WITH INJECTION AND SUCTION
Sinopsis
In the paper integral methods of calculating the turbulent boundary layer on permeable surface are analyzed and the regions of their applicability are found from the comparison of the analytical results with existing experimental data. Basic attention is paid to the analysis of the effect of complex boundary conditions on integral characteristics of the turbulent boundary layer. The efficiency of applying relative limiting laws of friction, heat and mass transfer to allow for a combined effect of transverse mass flow, variable physical properties, compressibility, longitudinal pressure gradient, surface roughness etc. is shown. The transpiration film cooling problems that are insufficiently studied at present are considered.
