Molybdenum disulfide nanoparticles suspended in water-based nanofluids with mixed convection and flow inside a channel filled with saturated porous medium

The shape effect of molybdenum disulfide nanoparticles suspended in water-based nanofluids with mixed convection flow inside a channel filled with saturated porous medium is studied. The radiation effect is also considered. One of the boundary walls of the channel is oscillating in its own plane. Four different shapes (platelet, blade, cylinder, and brick) of molybdenum disulfide nanoparticles inside a water, chosen as a conventional base fluid are used. The partial differential equations governed the problem are solved analytically by using perturbation method. Solutions for velocity and temperature are obtained and discussed graphically. A comparison of different shapes of molybdenum disulfide nanoparticles is analyzed. Results show that, nanoparticles with platelet and cylinder shapes have the highest thermal conductivity and viscosity compared to blade and brick shapes.
