PROCESSES IN A GAS CURTAIN

UDC 519.6:532:621.4

The authors give results of calculating the distribution 
of the efficiency of a gas curtain and heat transfer behind a row 
of individual orifices in a solid wall through which a coolant is 
injected into the main flow. A complete system of Navier-Stokes 
equations that are Reynolds-averaged and supplemented with a low-Reynolds 
k -  model of turbulence is used.
