A stimulus-response technique is used to determine particle-to-fluid heat transfer coefficient inpacked bed.The input signal is a one-shot thermal shock of arbitrary shape.Based on the D-C model,aFourier analysis method is applied.The result shows that in the laminar flow regime the Nusselt numberof particle-to-fluid heat transfer does not decrease appreciably with decrease in Reynolds number.
