This paper is framed to analyze mixed convection flow features of a CuO - H¹${}_2$O nanoliquid within a partially heated wavy enclosure. The enclosure is embraced by the inclined magnetic field. In addition, the impact of Brownian motion is assimilated into the nanoliquid. Two models, namely the viscosity and the thermal conductivity depending on the Brownian motion of nanoliquid are used. The numerical solutions of the control equations constituting Navier-Stokes equations are carried out by adopting a compact finite difference scheme. Our computed results using some experimental data are compared to the results available in the literature and a nice resemblance is obtained. Numerical results for the specified problem are investigated by controlling the key characteristics such as nanoparticle concentration ($0\le \varphi \le 0.04$), Richardson number ($0.1\le Ri\le 20$), Reynolds number ($50\le Re<750$), Grashof number ($Gr=5\times {10}^4$), Hartmann number ($0\le Ha\le 60$), orientation angle of magnetic field ($0^0\le \gamma \le {90}^0$), number of undulations ($0\le \lambda \le 3$) and amplitude of wavy surface ($A=0.05$). It is established that the angle $\gamma$ and the position of the heating area play a crucial role in the liquid motion and heat transport inside the wavy cavity. The energy transfer rate can be augmented or diminished in presence of nanoparticles along with variations of Hartmann and Richardson numbers as well as the number of waviness of the bottom surface of the enclosure.
