Heat transfer enhancement of mixed convection in a square cavity with inlet and outlet ports due to oscillation of incoming flow

Fuzzy-based estimation of mixed convection heat transfer in a square cavity in the presence of an adiabatic inclined fin

“…3. Comparison of the streamlines and isotherms for a cavity with all walls kept at temperature T h for Richardson number of 0.1 and 1, computed in [6] and computed with the current solver.…”

“…The global convergence for the continuity, momentum and energy residuals is set to 10 −4 , 10 −5 and 10 −5 , respectively. The chosen solver settings are tested for a square enclosure without fins with those of [6] for a Reynolds number of 300 (based on the width of the inlet port) for Richardson numbers of 0 and 10 in Fig. 3.…”

“…They also showed that for Strouhal number of 0.1, the mean Nusselt numbers on the four walls exhibit large amplitudes of oscillation, but at Strouhal number of 10, the amplitudes of oscillation on various walls are generally degraded. [6] have investigated the flow field and heat transfer characteristics in a square cavity with two ventilation ports for the mixed convection case. A pulsating velocity is imposed at the inlet port for a range of Strouhal numbers for Reynolds numbers between 10 and 500.…”

Buoyancy enhanced natural convection inside the ventilated square enclosure with a partition and an overhanging transverse baffle

“…Nusselt numbers are illustrated along the four walls simultaneously like Saeidi and Khodadadi [21] and Sourtiji et al [33]. Spatial co-ordinate system(S) is adopted as in Fig.…”

Numerical simulation of compressible high gradient thermobuoyant flow in square enclosures with localized heating from below

“…They considered various Rayleigh numbers and optical thicknesses, and concluded that even under normal room condition with a low temperature difference, the radiation has a major effect on the heat transfer rate and temperature and flow fields in the cavity. If besides buoyancy force, the convective heat transfer due to an external source contributes in heat transfer, the situation would be mixed convection which has also been focused by many researchers [13][14][15][16].…”
