“…Shuvo et al 21 investigated the steady entropy generation and mixed convective flow of nanofluid within an inclined lid-driven trapezoidal enclosure have been investigated numerically. The Reynolds, Grashof, and Richardson numbers, the tilt angle of the base wall, and the nanoparticle volume fraction are the primary parameters of interest in the present study.…”

Computational analysis is utilized to examine the effects of introducing nanoparticles to a square lid-driven cavity to enhance the hydro-magnet mixed convection. Constant temperatures are imposed along the square container’s vertical edges. Both the top and bottom surfaces are covered with insulation. The lid is thought to move in two ways: increasing or decreasing free convection. In addition, a horizontal magnetic field is applied uniformly. For various Hartmann numbers (Ha) (0:100), Richardson numbers (Ri) (0.001:10), and solid volume fractions (0:0.1), the results are reported. This research is based on a constant Grashof number (Gr) of 104. The effects of parameters, including the Richardson number, Hartmann number, solid volume percentage on the stream, isothermal lines, and local Nusselt numbers (Nu), were investigated numerically. In addition, given various parametric settings, the anticipated results for the average Nusselt (Nuavg) are shown and discussed. For all tested parameters, increasing the magnetic field makes the orientation of the lid more effective on heat and fluid movement. The magnetic field reduces heat and fluid flow. The heat transmission is aided by increasing the solid volume percentage. The effect of nanoparticles on flow and heat transmission is being studied. At Ri = 0.001, the effect of lid orientation is not significant. The highest reduction in heat transfer occurs when adding flow at Ri = 10, = 0, and Ha = 100.

“…frequent presence in industrial and engineering applications. This type of system is characterized by the horizontal movable wall and the fluid quality with high thermal properties (Rashidi et al 2021;Yeasmin et al 2022;Sivanandam and Marimuthu 2023;Hussain and Öztop 2021;Islam et al 2012;Shuvo et al 2022). Previous studies on this topic focused on the general shape of the chamber (Peng et al 2003;Albensoeder and Kuhlmann 2005;Nemati et al 2010;Esfe et al 2019), the shape of the hot objects placed inside the chamber (Khanafer and Aithal 2017;Khanafer and Aithal 2013;Kareem and Gao 2017), fluid quality (Hatič et al 2021;Chowdhury and Kumar 2023;Kefayati 2015) and the effects of internal and external forces (Oztop et al 2011;Hussain et al 2016;Chatterjee 2013).…”

The use of complex fluids is one of the modern techniques used in small devices in order to enhance their thermal performance. This paper is a numerical study of a complex fluid imprisoned in a chamber with two hot bodies exposed to a magnetic field of constant intensity. The upper and lower walls move horizontally at a constant velocity, while the lateral sides are thermally insulated. The numerical simulation of the system was achieved based on the finite volume method that solves the differential equations of fluid mechanics and heat transfer. Simulations were carried out under the following conditions: Re = 1 to 40, Ri = 0 to 100, n = 0.6 to 1.4 and Ha = 0 to 100. The study showed that the thermal activity of the two bodies is different and related to initial condition. Also, the effect of the magnetic field is strong in the case of shear-thinning fluids, while its effect is diminished in the case of shear-thickening fluids.
