Design and Evaluation of an Active Yaw and Turbulence Generation System to Produce Unsteady Flow in Automotive Wind Tunnels
… velocity data were obtained using two-component hotwire anemometry measurements that were spatially averaged. Yaw performance under different operating conditions, such as flap oscillation frequency and amplitude, was evaluated in terms of the phase-averaged flow behavior, the shape of the yaw …

Wind tunnel study of wind farms with alternating 2- and 3-bladed wind turbines
… velocity measurements were made with hotwire anemometry at various locations in the wake and the power output of turbines was measured simultaneously. Comparison of the flow between an array with only 3BT and that with alternating 2BT and 3BT shows enhanced mean velocity and reduced …

Interaction of High Aspect-Ratio Micro-Pillars with Wall Turbulence
… of HAMuP arrays with wall turbulence. Hotwire anemometry measurements were carried out in two different experimental facilities at three different streamwise locations to describe the interaction between the HAMuP array and the wallturbulence. There is a shift of the laminar sublayer …

Aerodynamics and aeroacoustics of flap side-edges
… pressures, particle image velocimetry, hotwire anemometry and on-surface microphones. Oil flow was performed to visualise the on-surface flow. A detached eddy simulation was performed on a geometry that consisted of a main element and a half span flap to understand the flowfield. From …

Spatially Resolved Analysis of Flame Dynamics for the Prediction of Thermoacoustic Combustion Instabilities
Increasingly stringent emissions regulations have led combustion system designers to look for more environmentally combustion strategies. For gas turbine combustion, one promising technology is lean premixed combustion, which results in lower flame temperatures and therefore the possibility of …

Effect of wall motion on a two-dimensional turbulent boundary layer
… of the freestream. Velocity measurements, using hotwire anemometry, are carried out at various locations upstream, on and downstream of the moving belt. A standard TSI boundary-layer probe is used. Mass transfer measurements are conducted using a naphthalene-coated sublimation plate, placed …
