The flow of a polystyrene Boger fluid through axisymmetric contraction–expansions having various contraction ratios (2 ≤ β ≤ 8) and varying degrees of re-entrant corner curvatures are studied experimentally over a large range of Deborah numbers. The ideal elastic fluid is dilute, monodisperse and well characterized in both shear and transient uniaxial extension. A large enhanced pressure drop a...

The goal of this research is to investigate the effects Ohmic heating, heat generation, and viscous dissipative flow on magneto (MHD) boundary-layer transmission flowing Jeffrey nanofluid across a stretchable surface using Koo-Kleinstreuer-Li (KKL) model. Engine oil serves as primary fluid suspended with copper oxide nanomolecules. governing equations that regulate fields are partial-differenti...

The heat transmission process is a prominent issue in current technology. It occurs when there temperature variation between physical processes. has several uses advanced industry and engineering, including power generation nuclear reactor cooling. This study addresses Maxwell fluid’s steady, two-dimensional boundary layer stream across linearly stretched sheet. primary objective of this resear...
