Abstract

An intention of the current study is to analyse the effect of double-diffusive convection in a hybrid nanofluid filled in an inclined open cavity with heat generation/absorption. The cavity walls are insulated whereas the centrally placed baffle is maintained at a high temperature. The CuO + MWCNT nanoparticles suspended in the water are used as a working hybrid nanofluid. The angle of inclination γ = 0°–90° is applied for the open cavity. The non-dimensional governing equation in the form of vorticity stream function transport is solved numerically by using the finite difference method. The behaviour of fluid flow, heat transfer, and mass transfer are presented as a contour. At various parametric conditions (q = −4 to 4, Br = −4 to 4, Le = 1–6), the average Sherwood and Nusselt numbers are calculated and explained graphically. The results report that an inclination angle suppresses the heat and mass transfer rate in an open enclosure.
