The modified method from the drift flux model is proposed to correlate the in-situ volume fraction of the solid phase in liquid・solid two-phase flow and in gas-liquid-solid three-phase flow. Though the settling velocity of particles in a stationary liquid has been usually related to the intercept with the axis of the mean solid velocity, V_s, the suspension velocity of particles in a flowing fluid is now related to the intercept with the axis of the total volumetric flux, j_γ, in the linear functional relation between V_s and j_γ. The applicability of this proposed method is verified well by the comparison of the calculated values with the experimental results of the in-situ volume fraction obtained in an aluminium particles-water two-phase flow and an aluminium particles-air-water three-phase flow in a vertical pipe 20.6 mm in I. D. and 6.4 m in length.
