Distributions of pressure and velocity in the main channels were studied in a radial flow cold model of a moving bed reactor, 500 mm in diameter, in four different gas flow modes, inward Z gas flow, inward Π gas flow, outward Z gas flow, outward Π gas flow. It has been found that, in outward Π gas flow mode, the axial non‐uniformity of the gas is at a minimum. The following correlations are proposed for the momentum recovery factors K a and K b : K a = 0.684 + 0.0128 (d u /d x )/ u , K b = 1.135 + 0.0158 (d u /d x )/ u . Pressure distributions in the main channels can be accurately predicted using K a and K b .
