We propose an anti-parity-time (anti-$\mathcal{PT}$) symmetric non-Hermitian Su-Schrieffer-Heeger (SSH) model, where the large non-Hermiticity constructively creates nontrivial topology and greatly expands topological phase. In anti-$\mathcal{PT}$-symmetric SSH gain loss are alternatively arranged in pairs under inversion symmetry. The appearance of degenerate point at center Brillouin zone det...

Diamond and graphene are carbide nanoparticles that have valuable biomedical applications in cancer therapy drug delivery. The aim of this study is to analyze the couple stress nanofluid (blood–graphene/diamond) flow an asymmetric channel with effect viscous dissipation, electromagnetohydrodynamics (EMHD), Joule heating, velocity slip convective boundary conditions. mathematical model solved an...

The presented article addresses the electro-osmotic peristaltic flow of a couple stress fluid bounded in an inclined asymmetric micro-channel. viscous dissipation, Joule heating and chemical reaction effects are employed simultaneously analysis. Heat mass transfer have been studied under large wavelength small Reynolds number. resulting nonlinear systems solved numerically. influence various do...

in this paper, we study the effects of hall and ion-slip currents on the steady magneto-micropolar of a viscous incompressible and electrically conducting fluid over a horizontal plate by taking in to account the viscous dissipation effects. by means of similarity solutions, deviation of fundamental equations on the assumption of small magnetic reynolds number are solved numerically by using qu...

The explosive viscous liquid becomes inject to warhead by discharge system. The injection device is consisted of a piston to move down and leads the viscous fluid through the cylindrical pipe towards the end of the duct. Then the viscous fluid leads into a convergent path that will be injected to the warhead or other injection equipment. In this project, the path of viscous fluid flow is divide...

This article investigates unsteady magnetohydrodynamic (MHD) mixed convective and thermally radiative Jeffrey nanofluid flow in view of a vertical stretchable cylinder with radiation absorption heat; the reservoir was addressed. The mathematical formulation is established based on theory boundary layer approximations pioneered by Prandtl. governing model expressions partial differential equatio...
