Abstract

The current work is being done to investigate the flow of nanofluids across a porous exponential stretching surface in the presence of a heat source/sink, thermophoretic particle deposition, and bioconvection. The collection of PDEs (partial differential equations) that represent the fluid moment is converted to a system of ODEs (ordinary differential equations) with the use of suitable similarity variables, and these equations are then numerically solved using Runge Kutta Fehlberg and the shooting approach. For different physical limitations, the numerical results are visually represented. The results show that increasing the porosity characteristics reduces velocity. The mass transfer decreases as the thermophoretic limitation increases. Increases in the porosity parameter reduce skin friction, increases in the solid volume fraction improve the rate of thermal distribution, and increases in the thermophoretic parameter increase the rate of mass transfer.

具有热泳粒子沉积的指数拉伸片上的生物转化纳米流体流动
目前正在进行的工作是研究纳米流体在存在热源/汇、热电泳颗粒沉积和生物对流的情况下通过多孔指数拉伸表面的流动。通过使用合适的相似变量,将表示流体力矩的偏微分方程集合转换为常微分方程系统,然后使用Runge Kutta Fehlberg和射击方法对这些方程进行数值求解。对于不同的物理限制,数值结果以直观的形式表示出来。结果表明,孔隙度特征的增加会降低速度。传质随热泳极限的增大而减小。孔隙率参数的增加降低了表面摩擦,固体体积分数的增加提高了热分布速率,热泳参数的增加增加了传质速率。
