“…Heat transfer in a pulsating laminar flow was also numerically studied and a variety of contradictory results were reported [24][25][26][27][28][29][30]. They have observed that at the fully established downstream region, the Nusselt number may increase or decrease according to frequency parameters.…”

In this article, a numerical study on heat transfer in laminar pulsating air flow in a channel around two discrete flush-mounted heat sources is reported. Simulations are conducted for five different frequencies and three different amplitudes while the Reynolds number (Re = 125) and Prandtl number (Pr = 0.71) remain constant for all cases. In addition, limited geometric parameters such as spacing between the two discrete heaters are investigated. Numerical simulations are performed by using the commercial CFD code Fluent. The optimum heat transfer parameters are analyzed. The time-mean Nusselt number is obtained for a cycle and given as dimensionless parameters. The heat transfer enhancements are found for low frequencies and high amplitudes.
