“…The role of interfacial nanolayer size on the natural convective heat transfer under magnetohydrodynamic effects were analytically determined by Benos and Sarris [38]. Also, the dissipative heat amounting due to the work done against viscous stresses become crucial when large variations in buoyancy forces exist [39][40][41].…”

The interfacial nanolayer effect on a mixed convection flow of single wall CNT (carbon nanotube) and CuO (cupric oxide) water based hybrid nanofluid inside a squeezed channel is studied. To maintain the flow, hybrid nanofluid under consideration is either squeezed or dilated in the parallel plate channel. Melting heat condition on one side of the channel is taken. Generalized thermophysical models which include the interfacial nanolayer effects are proposed for the hybrid nanofluid. Governing equations for the flow are tackled via similarity mappings and bvp4c technique. Statistical analysis revealed a strong significance of the interfacial ratio parameters with Nusselt numbers and skin friction coefficients at both ends of the channel. In case of squeezing flow, it is interestingly noted that the melting parameter uplifted the heat transfer rate, however reverse trend prevailed for dilating flow regime. Mixed convection parameter declined the rate of heat transfer in the squeezing channel, but elevated the coefficient of skin friction.

This paper deals with the effect of three-dimensional magnetohydrodynamic flow for a couple of stress fluids on an exponentially stretching sheet. The magnetic field is implemented normally to the surface. To observe the transfer of heat phenomenon, the Cattaneo-Christov flux model of heat is employed. Using similarity transformation, the substantial differential equations are reformed into ordinary differential equations. Eventually, the effects of different physical parameters are studied graphically. The drawback in Fourier heat flux model is removed by adding a new paramter known as thermal relaxation time by Cattaneo. This perimeter allows heat transportation by way of propagation of waves thermally at a defined speed. After this, the Cattaneo law is further modified by Christov-Christov to replace the ordinary derivative along Oldroyd's upperconvective derivative.

[20][21][22][23][24][25] Entropy generation is used to determine the performance of various isolated thermal systems in manufacturing, engineering, refrigerators, thermal transportation phenomenon, hybrid-powered engines, industrial, and various biological processes. Entropy production occurs due to fluids friction, Joule heating, diffusion, friction of solid surfaces, electric resistance, molecules vibration, unstained expansion chemical reaction, thermal resistance to the liquid flow, etc.…”

Here, we scrutinize the entropy analysis in magnetohydrodynamic flow of second-grade nanomaterials with melting effect subject to stretchable bended surface. Heat attribution is modeled through first law of thermodynamics with radiation effect. Major physical effect of random and thermophoretic motion is also addressed. Feature of irreversibility (entropy rate) analysis is also discussed. Isothermal cubic autocatalyses chemical reaction at catalytic surface is discussed. Nonlinear dimensionless differential system is developed through adequate transformation. Optimal homeotypic analysis method (OHAM) is employed to construct convergent solution. Influence of physical variables on entropy rate, fluid flow, concentration, and thermal field is discussed. An augmentation in fluid flow is noticed through curvature variable, while reverse effect holds for magnetic variable. A reverse effect holds for fluid flow and thermal field through melting variable. Entropy analysis is augmented with variation in melting variable. Reduction occurs in concentration through thermophoretic variable, while an opposite effect holds for thermal field. An increment in melting variable leads to reduced concentration. Larger estimation of radiation variable improves entropy analysis.
