Abstract This research conducts a study of natural convection heat transfer (NCHT) in a nanofluid under a magnetic field (MF). The nanofluid is in a cavity inclined at an angle of 45°. The MF can take different angles between 0° and 90°. Radiative

The present study numerically simulates the mixed convection of the hybrid nanofluid (HNFs) of Al2O3/CuO–H2O on a simple heat sink (HS). The (HNFs) flow passes on an isothermal HS. The NF flow was treated as a slip flow on the upper wall. A uniform

Fractional analysis provides useful tools to describe natural phenomena, and therefore, it is more convenient to describe models of satellites. This work illustrates rich chaotic behaviors that exist in a fractional-order model for satellite with and

The quiddity of ethylene glycol (EG) surface tension is attributed to the cohesive forces between EG molecules. The presence of tungsten oxide (WO3) nanoparticles certainly affects the cohesive forces and the surface tension will be affected. In this

In this paper, the exergy rate analysis at a pin–fin micro-heat sink (MH/S) is investigated numerically. The critical part of a MH/S contains several square-shaped pin–fins. A turbulent flow of water/boehmite alumina nanofluid (N-F) moves on the
