Abstract
The transient forced convection in tubulent channel flow with a step change in inlet temperature is solved by using a hybrid scheme, namely, by combining the generalized integral transform technique with a second-order accurate finite-differences. Stability and convergence of the scheme are examined. Numerical results are presented for the fluid bulk temperature and local Nusselt number as a function of position along the channel at different times, and the propagation of the thermal wave front during temperature transients is examined.
