Numerical investigation of mixed convective in a vented square cavity with fin. The horizontal walls are adiabatic, while the left and right walls are at hot and cold temperatures, respectively. The fluid inlet to the cavity from the lower left open area, and exit from the upper right open area. In this study, a finite element scheme is employed. The analysis is done for specific Prandtl number, Reynolds number, fin length, Richardson number, and the location of the fin. The finding indicates that the increases when high the location of the fin is, the increase at the maximum height of this fin location is estimated to be 17% due to an increase in the area of fluid flow on the hot wall caused by rising convective. The highest heat transfer occurs when the fin length is equal to 0.6 at the location.

With the aid of the COMSOL program, the laminar mixed convection heat transfer in a channel-open cavity with two heat sources of constant 20 W each and varying input air velocity ranges (0.1, 0.5, 1.0, and 1.5 m/s) is numerically determined. In this study, the effect of varying inlet air velocity on the heat transfer characteristics is investigated. Numerical results show that the temperature starts to fall steadily as one moves farther and further away from the site of the two heat sources and closer to the horizontal channel. The higher the velocity of the air entering the cavity, the greater the natural convection that will be created by the heated heat sources. The increase in inlet air velocity will increase the turbulence of airflow and thus increases the pressure distribution. The increase in absolute y-direction decreases the velocity distribution. The rise in the inlet velocity of air will increase the transfer of heat; thus, the Nusselt number will be great when increasing air flow velocity. The maximum Nusselt number is at the interface and reduces with increasing the absolute value of y. A reduction in air temperature and an increase in air density result from an increase in natural convection from the cavity into the air stream caused by an increase in air input velocity.

The thermo-hydraulic analysis of laminar mixed convection (forced and natural) through a horizontal channel-enclosure assembly equipped with a heated hollow hemispherical source (constant power of 20 W) in the bottom of the enclosure and different inlet air velocities equivalent to Reynolds number ranged (2.8814, 14.407, 28.814, and 43.221) are obtained numerically with the help of COMSOL Program. The impact of altering the input air velocity on the thermo-hydraulic properties is explored here as part of the research project. Good agreement was found between the derived numerical findings and those already established in the literature. The pressure profile throughout the channel is not altered via the numerically simulated increase on the positive y-axis. Increasing the incoming air velocity increases the natural convection induced via the heated source, which in turn increases the blending of cold and hot air within the enclosure and reduces the temperature gradient across the channel. As a result of the circumstances preventing slippage, the channel area exhibits the characteristic velocity profile of laminar flow, which consists of zero velocity at the channel walls and the maximum velocity in the channel's middle. The area of the recirculating streamlines is expanded by the rise in the velocity of intake air. As the incoming air velocity increases, so does the average Nusselt number.
