Abstract
The particular inquiry is made to envision the characteristics of magneto-hydrodynamic oscillatory oblique stagnation point flow of micropolar nanofluid. The applied magnetic field is assumed parallel towards isolating streamline. A relative investigation is executed for copper and alumina nanoparticles while seeing water type base fluid. To be more specific, in the presence of both weak and strong concentration, the physical situation of micropolar fluid is mathematically modeled in terms of differential equations. The transformed mixed system is finally elucidated by midpoint method with the Richardson extrapolation development and shooting mechanism with fifth order R–K Fehlberg technique. The impact of governing parameters are shown and explored graphically. The obtained results are compared with existing published literature. Moreover, it is found that the magnetic susceptibility of nanofluids shows provoking nature towards copper as compared to Alumina. Also it is perceived that Cu–water shows higher wall shear stress and heat transfer rate than Al2O3–water. Additional, the thickness of momentum boundary layer is thin for weak concentration as related to strong concentration.
Highlights
The study of nano uids claims remarkable practical applications in investigational and modern disciplines
Murshed et al.[2] observed that the operative thermal conductivity and viciousness of nano uids considerably enhanced by particle volume fraction
Numerical assessment is carried out towards model equations of water-based micropolar nano uid containing metals and oxide ceramics nanoparticles named as alumina (Al2O3) and copper (Cu)
Summary
Khan et al.[15] explore the magneto-hydrodynamic ow under the region of oblique stagnation point with slip effect for water-based nano uid containing, and (as nanoparticles). They found that –water is the source of enrichment of heat transfer at the sheet followed by –water and –water. It is important to note that some of these micropolar uids do behave as nano uid with heat transfer enhancement characteristics due to the presence of nanosize particles apart from their intrinsic polarities.
