Experimental study of alumina-water and zirconia-water nanofluids convective heat transfer and viscous pressure loss in Laminar regime
… was designed and constructed to operate in the laminar flow regime (Re<2000). Initial tests were conducted with deionized water for experiment validation. Alumina nanofluid was tested in the flow loop at four different volumetric loadings, 0.6%, 1%, 3% and 6% and zirconia nanofluid was tested at …

Computations of Flow Structures and Heat Transfer in a Dimpled Channel at Low to Moderate Reynolds Number
… on channel height) varies from Re = 25 in the laminar regime to Re = 2000 in the early turbulent regime. Fully developed flow and heat transfer conditions were assumed and a constant heat flux boundary condition was applied to the walls of the channel. In the laminar regime, the flow and heat …

An experimental study on mixing induced by gravity currents on a sloping bottom in a rotating fluid
… bottom formed a gravity current that could be in regimes where the flow was laminar or had waves. The mixing on a sloping bottom for gravity currents in the laminar and wave regimes was studied both qualitatively and quantitatively. The laboratory experiments were conducted on rotating tables in a …

Ferrofluid flow phenomena
… Ferrofluid flow through circular tubing in a laminar regime is examined as a function of the applied magnetic field magnitude, direction, and frequency. Gradients within the applied magnetic field create a magnetic contribution to the pressure drop across a length of tubing. Experiments of …

Scale-Up of Latex Reactors and Coagulators: A Combined CFD-PBE Approach
… coagulation of high solid content latexes in the laminar regime. It was found that changing the size of the reactor affected the latex PSD obtained at the end of the process. In the third part of the thesis, the framework was adapted to work with Fluent, a commercial CFD code, in order to …

Vortex-induced vibration of a linearly-sprung cylinder with nonlinear energy sinks
… that for values of the Reynolds number in the laminar regime (20 ≤ Re ≤ 350) and well into the turbulent regime (Re ≈ 10,000), the addition of an NES to a linearly-sprung cylinder undergoing transverse VIV gives rise to a variety of physical phenomena not seen otherwise. We consider two NES …

Numerical simulation and experimentation of pulsatile flows in axisymmetric arterial models
… In most of prior studies, a particular flow regime was selected and used throughout the entire solution domain. This selection ignored the fact that flowing fluids passing through variable cross sections undergo changes of flow regime. In particular, a flow initiated in a relatively large …

Experimental analysis of flow and turbulence characteristics in oscillatory boundary layers from LDV measurements
… Unlike steady boundary layer flows, the flow regime and bed roughness character of oscillatory flows change in time during the oscillation, a characteristic that introduces a high degree of complexity in the analysis. Experimental work in this topic started in the 1960s followed by numerical …

Semi-implicit schemes for compressible fluids in elastic pipes and a-posteriori sub-cell finite volume limiting techniques for semi-implicit Discontinuous Galerkin schemes for hyperbolic conservation laws on staggered meshes
… of highly unsteady viscous compressible flows in laminar regime in axially symmetric rigid and elastic pipes. We consider two families of differential models that can be used to predict the pressure and velocity distribution along the tube. One is the so called 2Dxr PDE model which is derived from …
