“…Torrance et al [9] investigated mixed convection in driven cavities as early as in 1972. Papaniclaou and Jaluria [10][11][12][13] carried out a series of numerical studies to investigate the combined forced and natural convective cooling of heat dissipating electronic components, located in rectangular enclosures, and cooled by an external through flow of air. The results indicate that flow patterns generally consists of high of low velocity re-circulating cells because of buoyancy forces induced by the heat source.…”

“…Unlike Φ=0º, when the buoyancy is acting only in the y direction, as the rotational angle Φ changes, the flow field changes significantly. In opposing flow condition the shear driven flow opposes the natural convective flow, At low Richardson number (Ri<1)the forced convection is dominating, creating a single circulation at the right corner of the top moving lid [figure [10][11][12]. As the Richardson number increases (Ri>1), natural convection becomes dominating creating a large circulation at the bottom of the cavity.…”

“…Studies in this field provide valuable support to address problems such as the ventilation in the presence of heat sources, as was underlined by Papanicolaou and Jaluria [1]. These studies have been applied to the chemical vapor deposition (CVP) technology and in the control of the propagation of fire and smoke.…”

An unsteady numerical investigation on mixed convection in a two dimensional open ended cavity with different aspect ratios is carried out. In this investigation, uniform temperature is set to the left and the right sides of the cavity while the other surfaces are adiabatic. The simulation is performed for a wide range of Reynolds numbers (Re = 100-1000) and Richardson numbers (Ri = 0.132-6.5 × 10 2 ), and various cavity aspect ratios (L/D = 0.5-4.0) and H/D = 0.1. Governing equations are solved using a cell centered finite volume code, a SIMPLE numerical projection scheme and a 2nd order accuracy. Results are presented in the form of streamlines, isothermal lines, and velocity profiles in the channel. The conclusion is that the enhancement of heat transfer rate is generated principally by the increasing Re and the assisting configuration is thermally more efficient when compared to the opposing one.

“…These types of problems also arise in electronic packages, micro electronic devices during their operations. Papanicolaou and Jaluria (1990) carried out a numerical study to investigate the combined forced and natural convective cooling of heat dissipating electronic components, located in rectangular enclosure and cooled by an external flow of air. At the same year, House et al (1990) considered natural convection in a vertical square cavity with heat conducting body, placed on center in order to understand the effect of the heat conducting body on the heat transfer process in the cavity.…”
