Abstract A numerical model is constructed to analyze the simultaneous development of the dynamic and thermal regimes of an incompressible viscous ducted flow under the influence of sinusoidal pulsations. The Navier-Stokes and energy equations are solved by a finite-difference method and by using asymptotic developments for the different dynamic and thermal functions. The model is validated by obtaining the Poiseuille regime for steady mean flow and by verifying Uchida's solutions for the unsteady dynamic components in fully developed flow. The model allows the description of Richardson's effect and depicts the existence of an annular effect for the pulsed temperature term.
