Abstract

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~.
