摘要:
Intensification of heat transport in a thermal system has attracted researchers nowadays. Among various methods, suspension of nanoparticles of distinct shapes plays a vital role in enhancing the heat transfer phenomenon. The aim of this study is to scrutinize the consequences of induced magnetic field on nanofluid flow in an horizontal microchannel formed by two parallel plates. Imports of heat source and convective boundary condition on flow and thermal field are deliberated. The modeled equations are nondimensionalized using dimensionless variables. The resultant nonlinear system have been computed via Runge- Kutta-Fehlberg method combined with the shooting technique. Magnetic and nonmagnetic nanoparticles are considered to pronounce the diverse flow and thermal properties. The upshots of the current investigations are visualized through graphical elucidation. It is established that rate of heat transfer is augmented for larger Biot number and heat source parameter. Also, it is verified that the Nusselt number at the upper plate of the microchannel satisfies the identity Nu(1Blade)>Nu(1Platelet) > Nu(1Cylinder) > Nu(1Brick).
