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.
