Heat transfer enhancement in stagnation point flow of ferro-copper oxide/water hybrid nanofluid: A special case study
Abstract
This present work is to investigate the behavior of Fe3O4−CuO/H2O hybrid-type nanofluid flow toward a magnetic field for enhancing the thermal transfer by horizontal stretchable surface. In the base fluid different tiny-sized nanoparticles collides and enhanced the heat transformation in the absence of magnetic field. Here the combinations of Fe3O4−CuO/H2O as hybrid nanofluids and CuO/H2O as nanofluid are implemented. The Ferro and Copper oxide are dispersed in water base fluid. Such Ferro nanomaterials are more fruitful in production technology, protein absorption, catalysis, medical technology and environment. The implementation of Fe3O4 NPs in medical science mainly involves targeted drug/gene delivery, biosensor, magnetic resonance imaging (MRI), contrast improvement and hyperthermia, biophotonics, detection of cancer cells, diagnosis and magnetic field-assisted radiotherapy and tissue engineering. Copper oxide used as a catalyst for increasing the rate of combustion in rocket propellant. It may significantly increase the homogenous propellant burning rate, lower the pressure index, and boost the effectiveness of the AP composite propellant as a catalyst. In additional, the governing coupled dimensional equations are reduced into the ordinary once with associated the suitable similarities. The resultant dimension-less expressions are programmed in the computational MATLAB software via bvp4c solver with shooting scheme. The important outcomes of this investigation are the behavior of numerous good parameters including stretching ratio parameterA∗, magnetic parameterβ, volumetric frictions for nanoparticlesφ, suction/injection parameterfw and thermal radiation parameterRd. The physical behavior of above discussed sundry parameters is described through figures. The dispersion of Fe3O4 and CuO in water-based fluid significantly improved the phenomenon of heat transfer. Results found that the velocity field is escalates when the stretching ratio parameter is enhanced. Furthermore, larger values of the suction/injection parameter causes a reduction in velocity profile for A1. The induced magnetic field is improved with larger estimations of the nanoparticle fraction. Thermal field is escalates by growing thermal radiation parameter and Eckert number. It is further observed that temperature profile is reduces by increasing stretching ratio parameter. From the analysis we noted that skin friction is raises via larger estimations of magnetic parameter.
