Heat transfer technologies are experiencing rapid expansion as a result of the demand for efficient heating and cooling systems in automotive, chemical, aerospace industries. Therefore, current study peruses an inspection mixed convective radiative Williamson flow close to stagnation point aggravated by single nanoparticle (alumina) from vertical flat plate with impact Hall. The water conveying...

Nanofluids are used as coolants in heat transport devices like exchangers, radiators, and electronic cooling systems (like a flat plate) because of their improved thermal properties. The preeminent perspective this study is to highlight the influence combined convection on transfer pseudoplastic non-Newtonian nanofluid flow towards an extendable Riga surface. Buongiorno model incorporated prese...

An experimental study on the flow of non-Newtonian fluids around a cylinder was undertaken to identify and delimit the various shedding flow regimes as a function of adequate non-dimensional numbers. The measurements of vortex shedding frequency and formation length (lf ) were carried out by laser-Doppler anemometry in Newtonian fluids and in aqueous polymer solutions of CMC and tylose. These w...

We study the finite-shear-rate rheology of disordered solids by means of molecular dynamics simulations in two dimensions. By systematically varying the damping strength ζ in the low-temperature limit, we identify two well-defined flow regimes, separated by a thin (temperature-dependent) crossover region. In the overdamped regime, the athermal rheology is governed by the competition between ela...

The relaxation of dilute polymer solutions following stretch in uniaxial extensional flow is investigated via Brownian dynamic simulations of a flexible freely-draining bead-rod chain. The bead-rod chain simulations are compared to Brownian dynamic simulations of a FENE dumbbell and numerical calculations of a FENE-PM chain. A universal relaxation curve for the stress decay from steady-state is...

This study performs extensive numerical simulations to investigate how the aspect ratio ( AR) of a lid-driven cavity influences onset elastic instability and turbulence subsequent mixed convective heat transfer rate inside it. To this end, we utilize finite volume method based open source code OpenFOAM along with Rheotool solve mass, momentum, energy, viscoelastic constitutive equations. We fin...
