摘要

本文对纳米液体在等速运动的纵向多孔翅片上的流动进行了数值模拟。镍合金被用作纳米颗粒,工程流体HFE 7100被用作基流体。此外,还考虑了各种形状的纳米颗粒,如球形、圆盘状和针状。对生成的常微分方程进行了无因次化处理,并用龙格-库塔-费贝格方法进行了积分。本文还通过作图讨论了合适的参数对强化传热的影响。同时,从数学上分析了不同形状纳米颗粒的影响。结果表明,球形纳米颗粒的传热性能优于圆盘状和针状纳米颗粒。

Nanoparticle shape effect on the thermal behaviour of moving longitudinal porous fin
A numerical examination of nanoliquid flow over a longitudinal porous fin moving with constant speed is undertaken in the current study. Nickel alloy is used as a nanoparticle, and engineered fluid HFE 7100 is used as a based fluid. In addition, various shapes of nanoparticles like sphere, disc and needle shapes are considered. The generated ordinary differential equation has been nondimensionalized and integrated by using the Runge–Kutta–Fehlberg method. The influence of suitable parameters on the enhancement of heat transfer has been discussed with the help of plotted graphs. Also, the influence of diverse shaped nanoparticle is analysed mathematically. It is found that sphere shaped nanoparticles show better transfer of heat than the disc and needle shapes.
