Illustration of thermal buoyancy on the flow of MHD Casson CNT–water nanofluids over a vertical stretching surface Mod. Phys. Lett. B (IF 1.9) Pub Date : 2024-02-28 Nilanchala Sethy, S. R. Mishra
This study addresses the applications of non-uniform heat source/sink and viscous dissipation in the magnetohydrodynamic (MHD) flow of Casson nanoparticles toward a porous stretchable sheet. The free convective flow for the inclusion of thermal buoyancy along with dissipative heat encourages the flow phenomena. The governing equations of the flow model are presented in terms of partial differential

The profound effect of heat transfer on magnetic peristaltic flow of a couple stress fluid in an inclined annular tube Mod. Phys. Lett. B (IF 1.9) Pub Date : 2024-02-28 M. M. Ahmed, I. M. Eldesoky, Ahmed G. Nasr, Ramzy M. Abumandour, Sara I. Abdelsalam
In this study, we explore the analysis of peristaltic flow with heat transfer occurring within the gap between coaxial inclined tubes. The inner tube’s wall is rigid, while the outer tube’s wall features a sinusoidal wave propagating through it. The cylindrical system is employed to formulate the problem. The flow is characterized using continuity, momentum, and energy equations. We apply the assumption

Raman-assisted Kerr platicon and perfect soliton crystal formation in the cavity Mod. Phys. Lett. B (IF 1.9) Pub Date : 2024-02-28 Xinyu Wang, Haoyu Zhang, Kegong Dong, Qiuhui Chu, Honghuan Lin, Jianjun Wang
In this paper, we investigate the soliton evolution dynamics influenced by the stimulated Raman scattering effect. The strong Raman gain ensures the breathing platicon and stable platicon formation at the cavity with normal quartic dispersion. The switching waves benefitted from the power transformation between pump mode and Raman gain spectrum could modulate the temporal waveform at the breathing

Stagnant points and uniform film analysis of Eyring fluid film flow on a vertically upward moving slippery flat plate Mod. Phys. Lett. B (IF 1.9) Pub Date : 2024-02-28 A. Walait, A. M. Siddiqui, H. Ashraf, I. Siddique, Hassan Ali Ghazwani, S. Jabeen
In this paper, we analyze how Eyring fluid film behavior on a vertically upward moving slippery flat plate can help predictive models in engineering, notably in coating and lubrication operations. This paper deals with the stagnant points and uniform film analysis of Eyring fluid film flow on a vertically upward moving slippery flat plate. The formulated ordinary differential equation is solved for

Broadband sound absorption using acoustic black holes with micro-perforated panels Mod. Phys. Lett. B (IF 1.9) Pub Date : 2024-02-28 Daxiang Meng, Xiao Liang, Haofeng Liang, Jiaming Chu, Zhuo Zhou, Guojian Zhou, Jianhong Duan, Jianwen Chen
In order to achieve broadband sound absorption, we propose a composite structure combining acoustic black holes (ABHs) and micro-perforated panels (MPPs). Here, we adopt both simulant and experimental methods to describe the sound transmission mechanism of the proposed composite ABH. This mechanism allows the ABH to have a sound absorption coefficient of over 0.8 in the range of 400–3200Hz and above

Effect of heat treatments on mechanical properties and wear resistance of laser-powder bed-fused Ti6Al4V alloy Mod. Phys. Lett. B (IF 1.9) Pub Date : 2024-02-28 Sen Wang, Linzhi Wang, Jing Li, Ting Li, Yingkun Qiu, Runqi Yang
The effects of heat treatment on the microstructure, mechanical properties and wear resistance of Selective Laser Melting Ti6Al4V alloy were systematically studied. The results show that the as-built part has an acicular α′ martensite structure. The increase in heat treatment temperature causes the decomposition of acicular α′ martensite, which leads to the decrease of the hardness of Ti6Al4V alloy

CsPbX3 photoluminescence enhancement by localized surface plasmon of Ag nanoparticles Mod. Phys. Lett. B (IF 1.9) Pub Date : 2024-02-28 Zongqin Wang, Yunyue Feng, Lei Song, Jun Dai
This paper investigates the enhanced photoluminescence of CsPbX3 by the localized surface plasmon (LSP) of Ag nanoparticles. The Ag nanoparticles with different sizes were obtained by annealing Ag thin films at different temperatures. Then the Ag/PMMA/perovskite structure was fabricated to realize the exciton-LSP coupling effect, and enhancement was found for wavelength-tunable CsPbX3 films. When the

Finite element simulations of Herschel–Bulkley visco-plastic materials over a cylinder: Drag and lift correlation analysis Mod. Phys. Lett. B (IF 1.9) Pub Date : 2024-02-28 Afraz Hussain Majeed, Imran Siddique, Asif Mehmood, Hassan Ali Ghazwani, Sajjad Manzoor, Shafee Ahmad
This study employs a two-dimensional and incompressible flow of Herschel–Bulkley visco-plastic materials in order to investigate the hydrodynamic forces that are acting on a barrier that is located close to the inlet of a channel. As the benchmark configuration, the flow domain that has been selected is a channel that still contains the impediment. The two important parameters of the Herschel–Bulkley

Evaluation of the influence of neighboring resonance on spectroscopy measurements Mod. Phys. Lett. B (IF 1.9) Pub Date : 2024-02-28 Ming-Chen Chen, Xiao-Qiu Qi, Ai-Xi Chen
The quantum interference arising from neighboring resonance is investigated in a four-level system. This effect is evaluated through two methods: one is the direct numerical solution of the optical Bloch equation, and the other considers the impact of neighboring resonances as perturbations on other equations, i.e., using a simplified approximate optical Bloch equation for simulation. The results show
