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.
