A numerical study of free convective heat transfer in a parallelogram‐shaped enclosure Available to Purchase

Two‐dimensional free convective flow in a parallelogram‐shaped enclosure has been studied numerically. The heated and cooled walls of the enclosure are isothermal and inclined at an angle β with respect to gravity. The top and bottom walls of the enclosure are horizontal and adiabatic. Calculations have been made for Rayleigh numbers ranging from 10³ to 10⁵ for a variety of wall angles (60° ≤β ≤60° ) and enclosure aspect ratios 0.5 ≤ A ≤ 3. Average and local Nusselt number results are presented for a Prandtl number of 0.7. Streamline and isotherm contours are also presented.
