AB In this study, a channel with a cavity heated from below and a left vertical side is numerically investigated for the mixed convection case in pulsating flow for a range of Richardson numbers (Ri = 0.1, 1, 10, 100) and Reynolds numbers of 300, 500, and 800 in the laminar flow regime. At the inlet of the channel, pulsating velocity is imposed for Strouhal numbers of 0.25, 0.5, 0.75 and 1 and velocity amplitude ratios of 0.7, 0.8, and 0.9. The effect of the pulsation frequency, amplitude, Reynolds number, and Richardson number on heat transfer enhancement is analyzed numerically. The results are presented in terms of streamlines, isotherm plots, and averaged Nusselt number plots. Transfer function plots for the Nusselt number response to single sinusoidal velocity forcing at the inlet and nonlinearity in the response is also provided.
