Study on time-dependent Oldroyd-B fluid flow over a convectively heated surface with Cattaneo-Christov theory

Muhammad Yasir et al.

Summary: The time-dependent two-dimensional Oldroyd-B fluid flow is investigated under the influence of generalized Fourier's and Fick's laws. The heat and mass transport mechanism is studied using the Cattaneo-Christov (CC) double diffusion theory, taking into account the thermal and solutal relaxation factors. The thermal conductivity of the fluid, which depends on temperature, is also considered. The flow equations are transformed into ordinary differential equations through suitable similarity transformations, and numerical integration is performed to visualize the effects of dimension-less physical constraints on the flow and energy transport phenomenon. The results show that the thermal and solutal penetration depth decreases with increasing flow controlling parameter and Lewis number, respectively.

Summary: This paper examines the impact of nonlinear thermal radiation on 2-D magnetohydrodynamic flow of hybrid nanoliquid across two distinct geometries and discusses the resulting flow and thermal distributions.

Summary: This study examines the phenomenon of entropy generation in the flow of magneto third-grade fluid through microchannels, with a focus on Joule heating, viscous heating, and internal heat sources. Using finite element methods, non-dimensional forms of governing equations for the physical phenomenon are solved, and the impact of various parameters on flow behavior, heat transfer, entropy generation, and Bejan number is explained through graphs. Results show that increasing fluid parameters decrease flow activity and temperature, while increasing viscosity index enhances fluid motion and temperature.
