This study reports both MagnetoHydroDynamics (MHD) and heat generation aspects of a water-based hybrid nanofluid flow with various shapes of the nanoparticles involving Nimonic 80A and Fe3O4, over a moving wedge. Similarity transformations were adapted to obtain non-dimensional equations and solved using MATLAB bvp4c code. All the results and graphs were formulated after a positive outcome of our results

Reaction–diffusion equation model in the electrical double layer for exploring the response signal in electrochemical sensing Mod. Phys. Lett. B (IF 1.9) Pub Date : 2024-03-27 Yanke Zhang, Wei Chen, Qingteng Lai, Zhengchun Liu
Electron transfer in the electrode–solution interface is responsible for the signal in the electrochemical sensor. However, the Electrical Double-Layer (EDL) characteristic is usually ignored in signal modeling. Here, we constructed a model based on the reaction–diffusion equation to describe the dynamics in the EDL during sensing. With this model, many common experimental phenomena, such as transient/steady-state

The wake characteristics and hydrodynamic forces of a near-wall circular cylinder with the splitter plate Mod. Phys. Lett. B (IF 1.9) Pub Date : 2024-03-27 Yulu Liu, Yubing Li, Jianghua Li, Jiankang Zhou, Xiang Qiu
Flow around a near-wall circular cylinder with the splitter plate is numerically performed at Reynolds number of 500, with the objective of investigating the wake characteristics and hydrodynamic forces. Five gap ratios G∕D=0.1,0.3,0.5,0.7 and 0.9 (G is the gap between the lower surface of the cylinder and the wall, D is the diameter of the cylinder) are selected, and the splitter plate length L∕D

Four-component combined integrable equations possessing bi-Hamiltonian formulations Mod. Phys. Lett. B (IF 1.9) Pub Date : 2024-03-27 Wen-Xiu Ma
This paper aims to generate a Liouville integrable Hamiltonian hierarchy by introducing a specific matrix eigenvalue problem with four components. The adopted approach is the zero curvature formulation. A bi-Hamiltonian formulation is furnished through applying the trace identity, which shows the Liouville integrability of the resulting hierarchy. Two examples of generalized combined nonlinear Schrödinger

In this paper, the rise behaviors of Taylor bubbles are investigated in sudden/gradual tubes filled with viscoelastic media via grid adaptive direct numerical simulations (DNS). The exponential Phan–Thien–Tanner (PTT) constitutive model is used to describe the viscoelastic rheological characteristics, and the phase interface is captured via the volume of fluid (VOF) method. The effects of tube structure

Lump–kink and hybrid solutions of the extended (3+1)-dimensional potential KP equation in fluid mechanics Mod. Phys. Lett. B (IF 1.9) Pub Date : 2024-03-23 Hengchun Hu, Yunman Tian
In this paper, the extended (3+1)-dimensional potential KP equation in fluid mechanics is studied through Hirota bilinear method. Many types of hybrid solutions, such as the lump–kink solution, lump-two kink solution and periodic lump solution are obtained by assuming different functions in the bilinear equation. The interaction solution between lump and triangular periodic wave is also derived by
