Heat Transfer and Flow Measurements in Gas Turbine Engine Can and Annular Combustors
… investigating the correlation between combustor flow field geometry and convective heat transfer at cold flow conditions for Reynolds numbers of 50,000 and 80,000. Flow velocities were measured using Particle Image Velocimetry (PIV) along the center axial plane and radial cross sections of the …

Total velocity vector measurements in an axial-flow compressor using a 3-component Laser Doppler Anemometer
… the rotor blade passage of a single-stage axial-flow compressor is reported. Measurements were made at four radial locations from 50% span out to the blade tip, and at seven different axial locations from -0.55 axial chord 1.40 axial chord. Measurements were made at only one throttle setting. The …

Inhomogeneous potential vorticity homogenization and equilibrium in simple models of baroclinic instability with implications for the extratropical circulation by Pablo Zurita-Gotor.
… and temperature for quasi-balanced stratified rotating flow. By rewritting the thermodynamic equation as a momentum equation, we eliminate the forcing by the mean meridional circulation and formulate a local balance between the eddy PV flux and the non-conservative forcing of momentum.

Modelling and diagnostic study of flow in an optical engine with negative valve overlapping for homogeneous charge compression ignition
… gas motion in an engine cylinder with different flow scales generates a varied range of shear stresses and deformations in the fluid, which leads to the gas turbulence. These flow irregularities combined with periodic engine operation induce gas fluctuations over time and cylinder volume. This …

CO2 Derived Carbon Capture Using Microalgae in a PhotoBioCREC Unit
… and photon energy utilization. Furthermore, the rotating flow design, in the near transmission wall region of the PhotoBioCREC prototype, was also demonstrated in a 10.3 L PhotoBioCREC Swirl Reactor prototype. It was proven in this PhD Dissertation, that this scaled-up unit could also benefit …

On convection and stability of some welding and solidification processes
… and experimental models purely poloidal flow bifurcates to a rotating flow. To investigate this possibility for our flow a linear stability analysis is performed on a numerically obtained poloidal solution for the flow and temperature distribution in a hemisphere (a model first derived in …

Experimental and numerical studies of whirling fires
… published results of theoretical analysis of rotating flames were oversimplified and based on strict limitations of the integral model or the inviscid flow assumption. Also there have only been few attempts to undertake CFD modelling of whirling flames. In published studies, radiative heat …

Rotating Thin Films: the Vortex Fluidic Device
… methods, i.e. confined mode (CM) and continuous flow (CF). In CM, a fixed volume of liquid is placed at the base of the VFD before rotation is initiated, with the characteristics of the film at steady state describing the fluid mechanics environment for most of the processing time. In CF, …

An experimental study of the spread of buoyant water into a rotating environment
… dynamics of the spread of buoyant water into a rotating environment. We focus in particular on the role that finite potential vorticity and background turbulence play in determining the flow properties. When water of an anomalous density enters into an oceanic basin, gravity-driven surface flows …
