The approach assumes that the flow consists of a sand bed and two mixture layers: liquid-continuous with dispersed particles and gas-continuous with dispersed droplets. The proposed model comprises one momentum equation for each mixture layer and four mass conservation equations: continuous liquid, continuous gas, droplets and sand particles, The multi-mixture model was validated against experimental in-house data,, A parametric study was presented; the parameters considered are liquid flow rate, gas flow rate, and pipe inclination. 收起
