Computational assessment of radiative flow of engine oil-based mono nanofluids between parallel infinite double disks

Abstract

Flow and heat transfer impacts of copper and silver are scrutinized between two infinite disks are addressed. The significance of mono nanofluids flow between double infinite disks is retained. The behavior of copper and silver nanoparticles and taking engine oil as a base fluid is scrutinized. A thermal radiation impact has been taken into account in heat equation. The governing equations of a MHD laminar flow among double disks are formulated in the presence of magnetic field. The suitable transformation is adopted to renovate the governing flow expressions into proper dimensionless ordinary differential equation. The renovated system in the form of dimensionless equations is numerically treated with the help of MATLAB via Lobatto-IIIa method. The role of different values parameters against flow and heat transfer is discussed in detail and elaborated graphically. From the outcomes, it is found that axial and radial velocity components has inverse trend for stretching parameter for lower and upper disk. Furthermore radial velocity is near the lower disk is reduce while boosts near upper disk for solid volume friction. It is observed that Pressure field is diminishes for larger Reynolds number. Stretching parameter for upper disk enhanced the pressure field. Temperature distribution is improves with larger stretching parameter for upper disk.
