On the nature of gas-particulate flow

Particulate compressibility and different particulate surface condition effects on the structure and overall characteristics of the gas-particulate boundary layer flow on a flat plate are estimated. Gas-particulate boundary layer equations are integrated by a Crank-Nicholson finite-difference scheme under various prescribed conditions. It is found that with particulate compressibility effects, particulate accumulation on the surface increases, normal velocity decreases with longitudinal distance on the plate and particulate boundary layer thickness decreases. Without particulate compatibility effects, the structure of the particulate flow depicts a physically realistic variation of all the various flow quantities, across the boundary layer.
