Complicated deformation simulating on temperature-driven 4D printed bilayer structures based on redu
The four-dimensional (4D) printing technology,as a combination of additive manufacturing and smart materials,has attracted increasing research interest in recent years.The bilayer structures printed with smart materials using this technology can re-alize
Flow of Eyring-Powell liquid due to oscillatory stretchable curved sheet with modified Fourier and F
This study deals with the features of the mass and heat transport mechanism by adopting a modified version of Fourier and Fick\'s model known as the Cattaneo-Christov double diffusive theory.The time-dependent magnetohydrodynamic (MHD) fiow of the Eyrin
A body force resembling the streamwise Lorentz force which decays exponen-tially in the wall-normalwise direction is applied in the primary and secondary separation bubbles to modify the base flow and thereby adjust the amplification rate of the perturba-
Optimization of heat transfer in the thermal Marangoni convective flow of a hybrid nanomaterial with
The heat transfer rate of the thermal Marangoni convective flow of a hybrid nanomaterial is optimized by using the response surface methodology (RSM).The thermal phenomenon is modeled in the presence of a variable inclined magnetic field,thermal radiation
In this study,a mathematical model is formulated to examine the blood flow through a cylindrical stenosed blood vessel.The stenosis disease is caused because of the abnormal narrowing of flow in the body.This narrowing causes serious health issues like he
Reiner-Rivlin nanomaterial heat transfer over a rotating disk with distinct heat source and multiple
The thermodynamic features of the Reiner-Rivlin nanoliquid flow induced by a spinning disk are analyzed numerically.The non-homogeneous two-phase nanofluid model is considered to analyze the effect of nanoparticles on the thermodynamics of the Reiner-Rivl
Bifurcation in most probable phase portraits for a bistable kinetic model with coupling Gaussian and
The phenomenon of stochastic bifurcation driven by the correlated non-Gaussian colored noise and the Gaussian white noise is investigated by the qualitative changes of steady states with the most probable phase portraits.To arrive at the Markovian approxi
The Liaoning clawed salamander (Onychodactylus zhaoermii) is an endemic and critically endangered amphibian species of China.To study the population genetics of natural populations of this species,32 samples were collected from six different locations,and
In many industrial applications,heat transfer and tangent hyperbolic fluid flow processes have been garnering increasing attention,owing to their immense impor-tance in technology,engineering,and science.These processes are relevant for polymer solutions,
Unsteady flow of a Maxwell hybrid nanofluid past a stretching/shrinking surface with thermal radiati
The non-Newtonian fluid model reflects the behavior of the fluid flow in global manufacturing progress and increases product performance.Therefore,the present work strives to analyze the unsteady Maxwell hybrid nanofluid toward a stretching/shrinking surf
