The added mass coefficient C is calculated for dispersed particles in different flow situations using the CFD simulations. Several geometrical configurations are considered, which are physically relevant and difficult to treat analytically. We study a single spherical and ellipsoidal particle near a gas/liquid interface, a pair of ellipsoidal particles in both the in-line and side-by-side arrangements,a nd an infinite array of spherical particles at different vertical and horizontal spacing.The effect of the key control parameters on the added mass is demonstrated. Where possible, easy-to-useclosed formulas(correlations) are provided for the value of C.
