Natural convection from open cavities or heated plates with parallel vertical strips is studied. The study uses steady, laminar numerical simulations of a heated cavity with adiabatic vertical walls, varying Rayleigh numbers (10³–10⁷), inclination angles (10°–90°), and aspect ratios (0.5–2.0) at Prandtl number 0.7. Results show that the average Nusselt number is largely insensitive to inclination angle, while flow destabilizes at high Rayleigh numbers and low inclinations, with detailed flow patterns and heat transfer discussed.
The present work is concerned with natural convection from open cavities or heated plates attached with parallel vertical strips. The bottom of the cavity is heated, and the vertical walls are assumed adiabatic. Numerical results are presented for steady, laminar natural convection for the geometry described. Effects of Rayleigh numbers from 1 × 10 3 to 1 × 10 7 , inclination angles from 10° to 90°, and aspect ratios of 0.5, 1.0, and 2.0 are investigated for a fixed Prandtl number (0.7). It is found that the average Nusselt number is not very sensitive to the inclination angle. Flow becomes unstable at high Rayleigh numbers and at low inclination angles. Flow pattern and heat transfer results are presented and discussed.
