摘要

Consideration is given to two systems of equations of transfer of correlations of particle-velocity and temperature pulsations, which differ in the method of closing. A closed description of the heat transfer of the solid phase is carried out at the level of equations for second moments in the first case and for third moments in the second case. A comparative analysis of the two methods of calculation of the ascending nonisothermal flow of a gas suspension is made based on numerical investigations.
