Effect of Corner Flow on Convective Heat Transfer in Inclined Cavity
Subscribe/Renew Journal
The effect of corner flow is investigated in an inclined square cavity numerically. Both clear domain and porous substance are considered in the cavity. The study is conducted under distributed heating and cooling arrangement applied on the four walls. This numerical study is carried out on a ventilated cavity providing entry and exit at diagonally opposite corners. On fluid dynamics, effects of various flow parameters like Richardson number (Ri = 0.1-20), Reynolds number (Re = 10-200), cavity inclination angle (γ = 0-180°), Darcy number (Da = 10-4-10-7) and porosity (ε = 0.3-1.0) are analyzed systematically. Streamlines, isotherms and average Nusselt number are utilized for exploring heat transfer of the cavity.
