;
The total heat transfer coefficient is measured between electrically heated bundles of tubes (12.7 and 28.6 mm diameter) and a square fluidized bed (0.305 x 0.305m) of silica sand and alumina. The staggered tube bundle has its tubes located at the vertices of equilateral triangles. The effect of particle size, mass fluidizing velocity (up to 0.66 kg/m/sup 2/s), tube pitch (1.75 to 9.00 times the tube diameter), and bed height on heat transfer rate is investigated.
