IMITATION RESEARCH ON LOCAL HEAT TRANSFER FROM HORIZONTAL TUBE BUNDLE IN HIGH TEMPERATURE FLUIDIZED BED

The theoretical research on heat transfer from horizontally staggered tube bundle in fluidized bed has not been found. For this reason,on the basis of experimental research,the paper puts forword and sets up a new methematic model,which gives good prediction to the local heat transfer coefficients and its variation around the tube surnace.
