摘要

本文研究了拉伸片上麦克斯韦纳米流体运动的粘性耗散。根据假设和新出现的参数,如磁性参数、热泳、布朗运动和 Biot 数等,构建建模等式。应用流函数将这些等式转换为简单的三阶 ODE,并使用 MATHEMATICA 软件,采用 RK 法和射击技术求解 ODE。通过纳入参数,以图表形式展示我们的成果。麦克斯韦流体的弹性与温度成正比,导致其速度降低。影响流体流动的因素包括粘性耗散、路易斯数、布朗运动以及温度和速度的可逆性。布朗运动参数的增加会导致纳米流体颗粒的显著运动,进而增加其动能,增强边界层的热量产生。洛伦兹力阻碍流体运动,导致速度曲线下降。这是由磁参数决定的。热传导率、速度衰减率和粘性耗散都发生在靠近薄片的地方。此外,所展示的模型表格验证和当前结果与之前发表的研究结果非常吻合。癌症治疗和工业冷却过程、聚合物加工、生物技术和医药、食品工业、化妆品、石油和天然气、纺织品、航空航天和汽车以及建筑业只是该技术在技术和生物方面用途的一小部分。各行各业可通过使用麦克斯韦流体模型,在各种应用中提高材料性能、工艺效率和产品质量。

Impact of viscous dissipation on MHD flow of Maxwell nanofluid across a linear stretching sheet
The viscous dissipation of Maxwell nanofluid movement on a stretching sheet is examined in the present article. Constructed the modelling equalities with assumptions and emerging parameters such as Magnetic parameters, thermophoresis, Brownian motion, and Biot number etc. Convert those equation to simple third-order ODEs by applying stream functions, MATHEMATICA software used to solve ODE by applying the RK method approach with shooting technique. Presented our outcomes graphically by incorporating the parameters. The elasticity of the Maxwell fluid is directly proportional to temperature, resulting in a reduction in its velocity. The factors that affect fluid flow include viscous dissipation, Lewis number, Brownian motion, and the reversibility of temperature and velocity. Increasing the parameters of Brownian motion leads to significant movement of the nanofluid particles, which in turn increases their kinetic energy and enhances heat generation in the boundary layer. The Lorentz force, which hinders the movement of fluid, leads to a decrease in velocity profiles. This is determined by the magnetic parameter. The heat transfer rate, the velocity decay rate, and the occurrence of viscous dissipation are all occurring in close proximity to the sheet. Also, the model tabular validation presented and current results align well with previously published studies. Cancer treatment and the cooling process in industries, polymer processing, biotechnology and medicine, food industry, cosmetics, oil and gas, textiles, aerospace and automotive, and construction are just a few of the technical and biological uses for it. Industries may enhance material performance, process efficiency, and product quality in a variety of applications by using Maxwell fluid models.
