“…Laplace transform technique has been utilized and results indicated the act of suction on perforated walls and the increase of oscillation frequency reduce the effectiveness of skin frictions on both walls of cylinder. Additionally, there is further research [6][7][8][9] conducted to investigate fluid flow and heat transfer in an annulus. Amouzadeh et al [10] surveyed analytically the influence of suction/injection on MHD fluid flow in a vertical annulus by considering radial heat generation or absorption with the aim of cooling electronic equipment.…”

In recent decades, reverse flow analysis in mixed convection flow has attracted many researchers' attention owing to its applications in the design of medical and engineering systems. The presence of reverse flow is unfavorable in many respects; therefore, it is crucial to find values of critical parameters affecting reverse flow to eliminate it. In this paper, the thermal and hydrodynamic behavior of MWCNT-Fe 3 O 4 hybrid nanofluid is explored in a vertical cylindrical annulus and in the adjacency of radial magnetic field by achieving the results of exact solution. Furthermore, the effective factors on reverse flow are investigated, considering the effects of wall movement and suction/injection on it. The range of changes of governing parameters includes constant velocity of cylinders' walls A=0−10, B=0−10, Mixed convection parameter η=-1500−1500, dimensionless temperature difference ratio ξ=0−1, Hartman number Ha=0−50, Suction/injection S=-6−6, nanocomposite particles concentration φ=0−0.3% and radios ratio λ=2−10. Results reveal that hybrid nanofluid enhances heat transfer rate. Moreover, by changing the above-mentioned parameters and selecting appropriate values for them, the flow, heat transfer and occurrence of reverse flow can be optimally controlled. Meanwhile, such parameters as Ha, S and ξ perform better in eliminating reverse flow.

An investigation of variable thermo-electrical field, viscosity, and thermal conductivity influence on blood rheological (Casson) fluid flow through micro annular channel subjected to suction/injection, slip, jump, and the nonlinear convective process is presented. The assumed steady, fully developed, and magnetized flow through the annular cylinder is modeled and non-dimensionalized under; Slip, jump, suction/injection conditions. Employing the Chebyshev collocation method, an approximate solution of the flow distributions is obtained. Parameters of interest indicate a declination of the flow field to a hike in variable thermal and electrical field parameters, appreciation to the risen value of viscosity parameter. Meanwhile, both momentum and energy distributions were promoted to a wider curvature radius.
