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 study focuses on the film deposition of Casson nanoliquid heat and mass transfer bioconvection flow, considering factors such as homogeneous-heterogeneous chemical reactions, entropy generation, thermal radiation, and magnetic dipole effects. The use of similarity transformations simplifies the governing equations and boundary conditions, while the homotopy analysis method is employed to obtain a series solution for the non-linear ordinary differential equations. The study investigates the effects of various parameters on the velocity, temperature, concentration of chemical reaction, motile microorganisms concentration, entropy generation, and spray rate.

Summary: This study investigates the effect of magnetic induction on the behavior of Ethylene Glycol-water based tangent hyperbolic cross nanoliquid flow above a porous stretched region. The presence of magnetic induction enhances the heat diffusion rate and thermal transmission of the nanofluid. The electromagnetic field plays a role in regulating the thermal and momentum fields.

Summary: A computational framework was used to study the drive and thermal transport of unstable MHD Oldroyd-B ferrofluid flow with CoFe2O4 nanoparticles in water. Results showed that spherical ferrous particles have higher energy transport efficiency compared to tube and laminar shaped particles, and the Nusselt number can be regulated by the Deborah number and unsteadiness parameter.

Summary: The study conducted a three-dimensional analysis of radiative Maxwell nanoparticles in the presence of microorganisms in a rotating frame through numerical analysis, and explored the impact of non-uniform heat sources and sinks on heat transfer phenomena using the Darcy-Forchheimer law for porous impact and inertial forces. The convective boundary conditions were utilized for simulated problems and a modified version of the Buongiorno nano-model was used to examine thermophoretic behavior and Brownian movement of nanoparticles.

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. The results show that nonlinear thermal radiation enhances thermal distributions and decreases heat transfer rates, with differences observed between flow over a cone and flow over a plate. Additionally, the thermal transport rate is significantly higher for flow above a cone compared to flow over a plate.

Summary: "This article introduces a novel approach by implementing the Tiwari and Das model on the Reiner-Philippoff fluid model, using the Cattaneo-Christov model and thermal radiative flow for heat transfer analysis. It addresses the gap in literature regarding the study of nanoparticles on fluid models past a stretchable surface. The results show that heat transfer rate increases with an increase in thermal radiation parameter, while the skin friction coefficient decreases with an increase in velocity slip parameter, demonstrating the importance of considering these factors in fluid dynamics research."

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. The influence of Hartmann number on local entropy generation rate and Bejan number is observed to be sinusoidal.

Summary: This study examines the flow of nanofluid containing multi and single-walled carbon nanotubes submerged in Ethylene glycol in a Darcy-Forchheimer permeable media over a stretching cylinder with multiple slips. The mathematical model takes into account non-uniform source/sink impacts, modified Fourier law, and autocatalytic chemical reaction. Entropy optimization analysis is performed and the nonlinear system is converted to ordinary differential equations for solution using the Shooting technique and bvp4c MATLAB software. The study shows that a strong magnetic field enhances temperature profile and decreases velocity profile, while fluid velocity decreases with increasing slip parameter. Additionally, entropy number increases with higher thermal relaxation parameter and Reynolds number.
