Detailed studies of the air and solid flow patterns in a spouted wheat bed have been made in column sizes up to 2 ft. in diameter. Orifice size, cone angle, bed height and air flow were varied so as to establish their effect on these flow patterns. Air flow within the bed was obtained from pressure drop gradients, and solid flow was obtained from particle velocity measurements taken at the wall. Pressure drop, air flow distribution between spout and annulus, solid circulation rate and flow line data are summarized. A correlation is proposed which relates pressure drop and particle velocity at the top of the bed with superficial air velocity at air flows above minimum spouting. Particle velocity measurements in the spout were made from photographs, and were calculated approximately from the drag equation for a single particle.
