Pulsed turbulent ducted air flows and related convective heat transfer are depicted by means of a numerical model. The mixing length hypothesis joined to the eddy viscosity and diffusivity model given by CEBECI, HABIB and NA is used. Turbulent transport properties are not supposed to change with time. The equation set is solved by means of a finite difference method coupled with asymptotical developments for the different physical quantities (pressure, velocity, temperature). Assuming a fully developed dynamic regime the developing steady and unsteady thermal fluid fields are described and consequently heat fluxes at the wall for a condition of uniform temperature.
