Abstract : The boundary layer of gas-particle flows in fields of changing pressures is analyzed. The analysis, which utilizes the momentum integral method, can be used to study the boundary layer of any particulate flow with incompressible gas-phase provided the flow properties outside the boundary layer are known. Numerical integration of the two momentum integral equations was carried out for the case of particulate flow in cascades. For this example, the results indicate that introduction of particles leads to an increase in the gas boundary layer thickness and that the gas boundary layer characteristics are usually more sensitive to particle concentration than any other particulate flow parameter.
