CALCULATION OF TURBULENT TWO-PHASE FLOW IN THE REGION 
OF IMPINGEMENT OF A FLOW ON A BODY

Averaged equations for gas suspension motion and equations 
of  the  k - epsilon  model  of  turbulence are reduced to 
a  closed  system  of  ordinary  differential equations in 
the region of impingement of  a  flow on a body. Numerical 
simulation of impurity motion and  heat  exchange  between 
a dust-containing gas flow and a wall in the  vicinity  of 
the  critical  point  is  carried  out.  The   effect   of 
the discrete component on the pulsation characteristics of 
turbulence is investigated.  Results  of  calculations  of 
the heat transfer coefficient as a function of  the  ratio 
of the heat capacities of the phases and the concentration 
and size of the impurity particles are presented.
