“…Ignoring the decrease in strength due to viscosity and normal magnetic material, a radial occurs inside. The equations [37] for continuity, momentum, and intensity that govern the general levitation and heat transfer situation are: Initially, the temperature of the inner cylinder is 400 Kelvin, the temperature of the outer cylinder is adiabatic, and the fluid is at atmospheric pressure of 300 Kelvin.…”

“…The current problem, however, may be extended to other simpler scenarios by modifying some parameters. Mohamed Deghmoum et al [37] provided a Bessel transform-based analytical solution for pulsating flow and heat transport in a pipe. Figure 2 depicts the velocity profile of the current research and that of Mohamed Deghmoum et al [37] at various t values.…”

Pulsatory movements appear in a variety of fascinating applications involving periodic flow propagation and control. Pulsing encourages mixing and, as a result, mass and heat exchange with the boundaries. Pulsing also helps to decrease surface fouling by allowing solid particles to migrate. An exact solution of the Navier–Stokes equations for the transport of an incompressible viscous fluid in a channel with arbitrary pressure distribution is described in this study. The flow is defined by two primary parameters: the pulsation parameter, which is determined by the periodic pressure gradient, and the kinetic Reynolds number, which is determined by the pulsation frequency. The purpose of employing hybrid nanofluid (HNF) is to increase the base fluid’s thermal conductivity. We regard Ag and Au as nanoparticles (NPs) and blood as a base fluid for this phenomenon. Broadening this reveals that the consideration of nanoparticles has impressively extended the warm movement at the parcels of both turbulent and laminar frameworks. Attention is paid to the slope of speed, temperature, and voltage. The geometric model is therefore described using a symmetry technique. We developed the governing equation for this problem’s analytical solutions. The velocity and temperature fields solution is given in the form of the Bessel and modified Bessel functions. Graph results show the mathematical benefits of the current limits: for instance, Hartmann number , solid volume part of nanoparticles , Reynolds number , Prandtl number , intermittent slob limit, etc. The strain angles introduced in the stress contrast, frictional force, velocity profile, and temperature profile were obtained, and the characteristics of the vortex were investigated. Resources at various boundaries of the perceptual flow are examined. As with the final essence, the smoothest results are analyzed and recorded. It has also been discovered that the velocity may be regulated by the external magnetic field, which affects the temperature profiles and hence the heat transfer, which can be enhanced or lowered by mastering the magnetic field.
