For faster speeds and higher load operations, modern bearings use lubricants with polymer components of increasing molecular weight. These exhibit non-Newtonian rheological behaviour. industrial lubrication bearing applications, power-law are often used. This article is modeled through the slip as an interfacial condition to demonstrate role on stagnation point flow magneto Jeffrey fluid. The significant features magnetic flux over lubricated surface studied control thermal mechanisms....

To maximize the efficiency of freezing, combinations using nanoparticles and fins have been utilized in current work. Incorporating nanofluids into solidification processes provides a refined efficient approach to transitioning materials from liquid solid state. Triangular container involving has implemented. The shape fraction were varied this research. derived equations solved via finite element method associated code validated based on prior article. reduction freezing time was presumed...

The goal of this paper is to determine the bulk acoustic wave (BAW) propagation velocities (quasi-longitudinal, quasi-shear vertical and horizontal) in two important piezoelectric smart materials, Lithium Niobate (LiNbO3) Tantalate (LiTaO3). To BAW velocities, elemental equations are deduced. calculated for each direction by solving Christoffel's equation systematically base d on theory waves anisotropic solids exhibiting piezoelectricity. modification piezoele ctric effect graphically...

<abstract><p>In this article, we extract stochastic solutions for the perturbed chiral nonlinear Schrödinger equation (PCNLSE) forced by multiplicative noise in Itô sense with aid of exp$ [-\varphi(\xi)] $-expansion and unified solver methods. The PCNLSE meditate on quantum behaviour, like features are closely related to its particular features. proposed techniques introduce closed form structure waves explicit form. behaviour gained qualitatively different nature, based physical...

This article extracts stochastic soliton waves for the perturbed nonlinear Schödinger’s equation (PNLSE) forced by multiplicative noise through Itô sense utilizing two unified solver methods. The presented solutions involve three types: rational function, trigonometric and hyperbolic function solutions. These are critical studying numerous complicated phenomena in heat transfer, new physics, many other fields of applied science. We demonstrate effect on solution PNLSE, which have never been...
