PROCESSES IN AXISYMMETRIC CHANNELS WITH A VARIABLE FLOW AREA

UDC 532.5

Consideration is given to the formulations of the primal 
and inverse problems of calculation of bubbling processes in axisymmetric 
channels with a variable flow area. A physico-mathematical model of 
motion of a bubble gas-liquid mixture and results of numerical calculations 
are presented.
