Abstract

Purpose: This aims to investigate heat and mass transfer characteristics of hybrid Nano fluid slip flow over a permeable sheet with radiative heat flux, variable thermal conductivity and heat source.

Methodology: Formulated Mathematical equations are transformed into self-similar equations using similarity transformation. Boundary value problem solver in MATLAB was used to solve the system of reduced similarity equations. In this study thorough examination was made on flow and heat transfer properties for various values of variable thermal conductivity parameter, thermal radiation and heat source. Validation of the present results with published results are in excellent agreement.

Findings: It is noticed that increase in radiative parameter attracts increase in temperature of the fluid at the shrinking region. It indicates that on shrinking region heat absorption take place with increase in value of variable thermal conductivity parameter (ℇ). The velocity of the fluid is appreciated with increase in silver volume fraction  and depreciates with increase in velocity slip parameter (P). Increase in velocity slip parameter decreases the local skin friction (P) and local Nusselt number is appreciated by increasing radiation parameter (R).Heat absorption is noticed with increase in variable thermal conductivity, silver volume fraction  and heat source/sink parameter (Q).

Practical implication: In practice the investigation of effects of hybrid nanofluid flow over a permeable sheet with radiative heat flux, variable thermal conductivity and heat source have real-life and industrial applications, for example manufacturing, cooling electrical devices, biomedical, military etc.

Keywords: Variable thermal conductivity, radiative heat flux, heat source, slip condition
