Abstract
This article deals with the analysis of the thermal-diffusion effect, chemical reaction and heat generation on the convective hydromagnetic flow of water-based nanofluid past an instantaneously accelerated infinite vertical plate nested in a porous medium. Simultaneous application of ramped temperature, ramped velocity, and ramped concentration has been considered. With the help of Laplace transformation, the set of transformed domain equations has been resolved. The consequences of various flow parameters involved in the study are analysed graphically. The results exhibit that the hydrodynamic and solutal boundary layer elevates for the higher value of the Soret effect Sr. Moreover, the rate of heat transfer hikes and on the other hand, the rate of mass transfer drops on account of the volume concentration of nanoparticles φ. Again, it is observed that the temperature, concentration and velocity field are dominated in the ramped condition by that of the isothermal condition.
本文分析了水基纳米流体流经嵌套在多孔介质中的瞬时加速无限垂直板时的热扩散效应、化学反应和热量产生。研究考虑了同时应用斜坡温度、斜坡速度和斜坡浓度的问题。在拉普拉斯变换的帮助下，解决了变换域方程组。对研究中涉及的各种流动参数的后果进行了图解分析。结果表明，索雷特效应 Sr 值越高，流体力学和溶质边界层越高。此外，传热速率上升，另一方面，纳米粒子的体积浓度 φ 导致传质速率下降。同样，在斜坡条件下，温度场、浓度场和速度场都受等温条件下的温度场、浓度场和速度场的支配。
