In this paper, we examine the effect of thermal radiation on rotating magnetohydrodynamic two liquid flows of ionized gasses past horizontal channel under slip and Hall conditions. The fluids in the two zones are considered to be immiscible, incompressible, and electrically conducting with various viscosities, thermal and electrical conductivities. We derive the exact solutions for the temperature profiles and coefficients of heat transfer rate at the plates in the two zones by solving governing equations in the presence of slip‐regime analytically. The temperature fields have been figured for various sets of values of the involved governing characteristics to analyze the behavior of heat transport. It has been noted that there is an enhancement in the temperature profile as the slip parameter rises for fixed values of the remaining parameters. Also, stimulations occur in the temperature field, with an increment in Taylor's number. This study may have some significant implementations in biomedical science such as destroying cancer cells during the drug delivery treatment, polishing damaged internal cavities, heart valves, and so forth.

In a rotational model, the Hall effect on two‐liquid magnetohydrodynamics plasma flows of ionized gases between two nonconducting horizontal channel plates in a slip regime is researched. The produced magnetic field is omitted under the presumption that the Reynolds magnetic number is low. The modeled governing equations are solved by using the existing analytical method so as to obtain solutions in closed form. We use the first order slip to obtain exact results for the velocity, temperature fields, and hence the rates of heat transfer coefficient. On the basis of different values for the Hartmann number, slip, Hall, and rotation parameters, also viscosity, density, height, and electrical conductivity ratios of the two fluids, a parametric investigation of the velocity, temperature fields is initiated. It was concluded that the velocity declined with the augmented values of Hartmann number and the fluid velocity and temperature profiles in both the zones oscillate with the effect of the Hall parameter. In addition to that, the stimulations are present in the heat transfer coefficient rate with various values of the slip and rotational parameters.

Irreversibility analysis for Casson thermo‐fluidics inside a cone: Cattaneo–Christov heat flux

In this communication, thermodynamic irreversibility arising in dissipative Casson fluid flow inside a cone is investigated. The boundary-layer flow is considered wherein the motion is caused due to a point sink at the cone's vertex and the movement of the wall of the cone.The wall of the cone is subjected to mass transpiration that alters the flow and thermal regime. The cone having fluid-saturated porous medium experiences Cattaneo-Christov heat flux. The configuration admits a similarity transformation that yields a boundary value problem (BVP) comprising an ordinary differential equation. The BVP is treated by the fourth-order R-K method along with the shooting algorithm. The system yields a dual solution for momentum and energy, which gives rise to a dual regime for entropy distribution. Numerical computations provide quantities of interest viz. velocity and temperature distributions, skin friction coefficient, Nusselt number, and entropy distribution. Phenomena exhibited through profiles/tables for velocity, temperature, entropy, streamlines, and other quantities of interest reveal interesting results.
