The effects of tube bank configuration on forces and heat transfer were investigated for both two-dimensional and three-dimensional gas fluidized beds.Effective dynamic forces and heat transfer coefficients were measured for several tube bank configurations,and it was found that the average forces are smaUer than for a single tube.The heat transfer coefficient can be increased by providing sufficient space for particles to descend around both sides of the tube bank.The results provide useful guidelines for optimizing the configuration of tube banks to achieve high heat transfer coefficients while reducing tube erosion due to dynamic forces.
