Thermal energy transport in Burgers nanofluid flow featuring the Cattaneo–Christov double diffusion theory

Abstract

In this article, the heat transport mechanism in the Burgers nanoliquid flow above stretchable sheet is investigated under the influence of uniform transverse magnetic field. For the analysis of thermal and solutal energy distributions, we have employed the Cattaneo–Christov double diffusion theory instead of Classical Fourier’s and Fick’s laws. The Buongiorno model for movement of nanoparticles in Burgers liquid is first time utilized in the perspective of Cattaneo–Christov model. Suitable similarity transformations are employed to transform the governing partial differential equations into ordinary differential equations. Homotopic approach is being utilized to expose the effects of different physical parameters on the flow of Burgers nanofluid. The results pertained by homotopic analysis method are depicted in the form of graphs and discussed with reasonable judgments. The validity of the homotopic approach is make sure by depicting comparison tables. Furthermore, it is analyzed that the thermal and solutal distributions of Burgers nanofluid are diminished by escalating the magnitude of thermal relaxation time and solutal relaxation time parameters, respectively. Additionally, the enhancing trend of thermal and solutal distributions is being perceived for higher strength of thermophoretic force.
