“…In this respect, numerous investigations were reported in the literature to identify this subject 5 – 8 . Cao et al 9 examined the natural convection of nanoliquid within a square heat exchanger chamber supplied with two cylinders that functioned as heaters and coolers on both sides in the application of magnetic intensity. The obtained results declared that the Rayleigh number ( Ra ) number, magnetic intensity, and inclination angle have an effect on the nanoparticles' movement.…”

Enhancing heat transfer rates within enclosures is a topic of considerable interest since it has several technical applications. Most heat transfer research projects focus on increasing the heat transfer rates of thermal systems since this will raise the systems' total efficiency. The geometry of the enclosure might have a substantial impact on heat transfer rates. This research studies quantitatively the natural convection of a nanofluid in a complicated form geometry with many baffle configurations. The system's governing equations were addressed by the Galerkin Finite Element Method (GFEM). The main consideration was given to the effects of the following factors: The Darcy number (Da), which ranges from 10–2 to 10–5; the Hartmann number (Ha), which ranges from 0 to 100; the volumetric fraction (ϕ), which ranges from 0 to 0.08, and the Rayleigh number (Ra) (102 to 106). The results suggested that raising Ra increases heat transfer discharge, whereas raising Ha and Da decreases it. In terms of heat transmission, case 1 (the case with a wavenumber of 1 and the zigzag pointing outward) is determined to be the optimum cavity structure, as it obtained the highest mean Nusselt (Nuavg) number when compared to other cases. At the highest studied Ra number, growing (ϕ) from 0 to 0.8 improved Nuavg by 25%, while growing Da from 10–2 to 10–5 and Ha from 0 to 100 declined Nuavg by 57% and 48%, respectively. The reason for the improvement in the values of the (Nu) is due to the speed of fluid movement within the compartment. Also, the shape of fins plays a major role in strengthening and weakening thermal activity.

In this article, the convective flow in a vertical layer subjected to a consistent magnetic field with nonzero gravity condition is investigated. One side of the vertical walls is heated, while the opposite side is cooling. The magnetic field strength, field orientation angle, magnetization effect, and thermal deviation of vertical walls play important roles as controlling parameters on the flow stabilization. The goal of this investigation is to analyze the flow characteristics and find out the significant distinction between water and kerosene based magnetic fluids under the variation of thermal and magnetic effects. The numerical results are obtained by the pseudo-spectral Chebyshev expansion method. The properties of all instability modes caused by three major mechanisms, namely; thermomagnetic, thermogravitational and magneto-gravitational are analyzed. In the normal magnetic field, the wave speed responds faster, and it is recognized by a relatively small wave number in water based fluid than that in kerosene based fluid. In oblique magnetic field, the waves propagate faster in both kerosene and water based fluids with the field inclination angle increases, but they still propagate slower in kerosene based fluid comparatively in water based fluid. According to the linear or non-linear magnetization law, both upward and downward propagating waves in kerosene based fluid propagate slower, and they are recognized by greater wave numbers than that in water based fluid. It is found that the basic flow in water based fluid is much more stable than in kerosene based fluid.

In order to figure out the interior construction and intricacy of nonlinear physical events in the real world, exact solutions and traveling wave solutions of the nonlinear equations are very crucial. The modified simple equation technique is a powerful and proficient technique for investigating traveling wave solutions of nonlinear equations found in applied mathematics, science and engineering. Exact solutions and traveling wave solutions allow researchers to predict the activities of the system under different circumstances. The aforementioned technique is utilized to investigate exact and traveling wave solutions for three important equations: the first-extended fifth-order nonlinear equation, the nonlinear medium equal width equation, and the Caudrey–Dodd–Gibbon equation. Here we obtained kink shape solution, singular kink, periodic solutions, bell shape solution and compacton solutions. The above approach performs better than other approaches nowadays in use in terms of consistency, competence, and effectiveness.
