This communication reports, the flow of viscoelastic nanofluid with third order slip flow condition, Cattaneo-Christov heat and mass diffusion model. The joined non-linear ordinary differential equations (ODEs) were acquired from the partial differential equations, which are resulting from conservation of momentum, energy and species. By means of similarity transformations these ODEs were alerted into dimensionless form and solved numerically by means of bvp4c solver. The effects of different parameters on velocity, temperature, and concentration profiles were examined and discussed in depth by means of graphs and tables. The outcomes indicate that the velocity profile along both x and y directions augment with higher values of viscoelastic parameter. The results also confirm that an increment in the values of ratio parameter tends to grow up the velocity profile alongside y-direction. However, the velocity profile along x-direction slows down with increment in the value of third order slip parameter. Also, the results illustrate that diminution in temperature is observed for higher Sc in the region of boundary layer. Besides, both temperature and concentration can be improved via higher Biot number. The upshots also portrayed that the local skin friction coefficient augmented within mounting values of viscoelastic fluid parameter. Furthermore, for finer values of Biot number both local Nusselt number and the local Sherwood number are enlarged. In addition, the most favorable agreement is observed among the results of the present study and those of the earlier studies.

三阶滑移条件下粘弹性纳米流体的流动分析,Cattaneo-Christov 热和质量扩散模型

该通讯报告了具有三阶滑移条件的粘弹性纳米流体的流动,Cattaneo-Christov 热和质量扩散模型。连接非线性常微分方程 (ODE) 是从偏微分方程中获得的,这些方程是由动量、能量和物种守恒产生的。通过相似变换,这些 ODE 被警告为无量纲形式,并通过 bvp4c 求解器进行数值求解。通过图表和表格深入检查和讨论了不同参数对速度、温度和浓度分布的影响。结果表明,沿xy的速度剖面方向随着粘弹性参数的更高值而增加。结果还证实,ratio 参数值的增加倾向于沿着y方向增大速度剖面。然而,随着三阶滑移参数值的增加,沿x方向的速度分布变慢。此外,结果表明,对于较高的Sc观察到温度降低在边界层区域。此外,温度和浓度都可以通过更高的比奥数来提高。结果还描绘了局部皮肤摩擦系数在粘弹性流体参数的安装值内增加。此外,对于更精细的 Biot 数值,本地 Nusselt 数和本地 Sherwood 数都会被放大。此外,在本研究的结果和早期研究的结果之间观察到最有利的一致性。
