Computation fluid dynamics on drag reduction II
Published 2011“…Both the flow pattern in the form of velocity contours and the quantitative drag coefficient are extracted and compared in several ways: single dimple along the wall with depth (h/D = 0.21); multiple (three) dimples along the wall with different separation distances between adjacent dimples; single dimple but with several other h/D ratios (i.e. 0.25, 0.14, 0.10, 0.08). …”

Turbulent Flow over a Flexible Wall Undergoing a Streamwise Traveling Wavy Motion
Published 2005“…For negative c/U, we find that flow separation is enhanced and a large drag force is produced. For positive c/U, the results show that as c/U increases from zero, the separation bubble moves further upstream and away from the wall, and is reduced in strength. …”

An experimental and simulation study of chip transportation behaviour in gundrilling
Published 2017“…From the experiments, terminal velocities of typical gun drill chips at different range of particle Reynolds number were determined to construct the unique drag curve. Based on the findings, a computational fluid dynamic (CFD) numerical model was developed to predict the lateral drag forces with respect to the particle Reynolds number. …”

Slow viscous flow around two particles in a cylinder
Published 2022“…The two solutions are performed in an iterated framework using the method of reflections. We compute the drag force and torque coefficients of the particles which are dependent on the distances among the cylinder wall and the two particles. …”

Essays on the market for corporate bonds
Published 2017“…Realized measures of volatility have been shown to be important in modelling and forecasting equity, exchange rate, and Treasury bill return volatility. We merge the NYSE's TAQ database of high frequency equity prices with the TRACE database, and show that the information contained in high frequency data is valuable in modelling the dynamics of the firm-level covariance matrix of bond and stock returns, for over 100 individual U.S. firms.…”

The unintended consequences of improving police recording of rape in England and Wales
Published 2024“…A strong focus in recent policy and media coverage has been the increase in reporting of rape coupled with an associated fall in the charge rate, often attributed to victim withdrawal. Drawing on an analysis of 741 police case files as part of Operation Soteria we question each of these positions. …”
