Abstract

Our numerical study is summarized on the effect of the inclination angle of the vibratory excitation and the magnetic field in a cavity filled with a nanofluid. The objective of our work is to optimize the value of the angle which ensures proper cooling of electronic components. The selected model is a square enclosure filled with a water-Al2O3 nanofluid subjected to vibratory excitation and a magnetic field at the same time inclined. The horizontal walls are maintained at constant temperatures, and the vertical walls are adiabatic. The system of equations that govern the problem is solved by the finite element method using the commercial software: Comsol Multiphysics. The results obtained are discussed in a range of inclination angle of the vibratory excitation and the magnetic field between 0 ° to 90 °.
