“…Sreedevi and Sudarsana [13] studied entropy generation and heat transfer simulation of 𝐴𝑙 2 𝑂 3 and carbon nanotubes-based hybrid nanofluids in a square shape enclosure, heat transfer rates increase from 8.20% to 17.60% when the solid-volume fraction was 0.05 in case of carbon nanotubes and heat transfer rates increases from 8.20% to 12.40% when 𝐴𝑙 2 𝑂 3 suspended nanofluid with the volume fraction 0.050 was used. Soomro et al [14] reported the findings of the study of mixed convection heat transfer within a lid-driven semicircular shaped cavity and revealed that raising the Richardson number reduces heat transfer rates while increasing the Hartman number increases heat transfer rates. In a wavy-shaped cavity, non-Newtonian hybrid nanofluid was numerically examined by Hussain et al [15].…”

Heat transfer occurs as a result of density differences caused by temperature changes. It has several industrial applications. To improve performance, one must investigate the heat transfer behaviour of the working fluid. Hence, the purpose of this work is to report a heat transfer analysis of a partially heated trapezoid cavity filled with a hybrid nanofluid. The temperature conditions of the cavity are such that the bottom boundary is partially heated, inclined side boundaries are kept at a lower temperature, and the upper boundary is kept adiabatic. A trapezoidal shape heated obstacle is considered in the cavity’s centre. The heat transfer and flow take place inside the cavity due to density variation. The mechanism is regulated by mass, momentum, and energy conservation, as well as related boundary constraints. The solutions are determined by the use of a numerical technique known as the Finite Element Method after the governing equations are transformed into non-dimensional form, which brings up physical parameters affecting the heat transfer and flow. The initial study is performed for three types of nanofluids with silver 𝐴𝑔 and magnesium oxide 𝑀𝑔𝑜 nanoparticles inside water 𝐻2𝑂, kerosene 𝐾𝑒, and engine oil 𝐸𝑂. The study revealed that the engine oil-based hybrid nanofluid produced an increased heat transfer rate. Simulation is performed using engine-based hybrid nanofluid with the range of physical parameters, such as Rayleigh number 𝑅𝑎 (105≤𝑅𝑎≤107), Hartmann number 𝐻𝑎 (0≤𝐻𝑎≤100) and nanoparticles volume fraction 𝜙 (0≤𝜙≤0.2). It is found that the heat transfer rate is enhanced by increasing the fraction of nanoparticles in the base fluid. Moreover, imposition of magnetic field has reverse impact on the fluid movement.

“…They observed that the direction of moving wall is not influenced by flow and heat transfer subject to the slip parameter. Soomro et al 12 examined the flow behavior of MHD mixed convection inside a water filled semicircular cavity containing a cylindrical obstacle. The results demonstrated that the presence of cold obstacle causes the splitting of water flow in two parts.…”

The magnetohydrodynamic flow of an incompressible, steady and electrically conducting fluid is considered in double lid-driven square cavity under an inclined magnetic field. The non-dimensional governing equations are solved numerically using a radial basis function (RBF) approximation meshless method in order to obtain the flow patterns. Hartmann number [Formula: see text] and the inclination angle of magnetic field [Formula: see text] are taken as a problem variables that produce various flow transformations by their variation for [Formula: see text]. Streamlines are examined topologically, and it has been observed that the inclination angle and strength of magnetic field have different influence on the bifurcation of flow structures.
