Numerical investigation on 2D viscoelastic fluid due to exponentially stretching surface with magnetic effects: an application of non-Fourier flux theory

Abstract

Two-dimensional flow of Casson fluid toward an exponentially stretched surface in view of Cattaneo–Christove flux theory is discoursed in current communication. Flow pattern within boundary layer under the effectiveness of magnetic field is also contemplated in the communication. Non-dimensionalized governing expressions are attained through transformation procedure. To anticipate the fascinating features of present work, solution of resulted nonlinear differential system is computed with the collaborated help of shooting scheme and Runge–Kutta method. The influence of involved variables on velocity and temperature fields is scrutinized. Contribution of thermal relaxation is explicitly pointed out. Evaluation of convective heat transfer and friction factor in the fluid flow is visualized through graphs and tables. Additionally, the assurance of present work is affirmed by developing comparison with previous findings in the literature which sets a trade mark for the implementation of numerical approach. It is inferred from the thorough examination of the analysis that present formulation reduces to classical Fourier’s problem by considering . Furthermore, decreasing pattern in temperature distribution is depicted in the presence of Cattaneo–Christove flux law as compared to heat transfer due to the Fourier’s law.

MHD rotating flow of a Maxwell fluid with Arrhenius activation energy and non‐Fourier heat flux model

“…Clearly, for , the simple Fourier's law of heat conduction is obtained from the dimensionless Cattaneo–Christov heat flux model. This result is in good agreement with Bilal et al 9 …”

“…Figure 7 shows the effect of Prandtl number and rotation parameter on the temperature profile. The temperature of flow diminishes for rising values of both the Prandtl number and the rotation parameter and a similar behavior was observed by Bilal et al 9 …”

“…The structural steadiness as well as uniqueness for non‐Fourier heat flux is studied by Ciarletta and Straughan 8 . Bilal et al 9 parametrically studied the behavior of a viscoelastic fluid by taking into consideration a Casson fluid together with the consequences of the magnetic field. Through his study, he acclimatized the non‐Fourier heat flux hypothesis on fluid flow.…”

“…in the presence of thermally stratified dual convection. In consideration of fluid flow induced by exponential stretching, a numerical investigation on 2D viscoelastic fluid flow due to an exponentially stretching surface with magnetic effects was carried out by Bilal et al . from which it was discovered that temperature profile decreases with an increase in temperature exponent parameter.…”
