Heat transfer enhancement in drag-reducing channel flow by Yeo, Keng Hoo

“…In the present study, a two-dimensional water tunnel was designed and fabricated to investigate drag reduction by surfactant additives. Flow development check experiments were performed with different concentrations of surfactant additives to justify the fully developed flow conditions at the test section. …”

Wind tunnel testing of a ducted-fan unmanned aerial vehicle by Shiah, Zi Yang.

“…The experiments were carried out in a closed-loop wind tunnel with the full-scale MAV at different configurations. Coefficients of lift, drag and pitching moment were first discussed in a simple configuration of varying pitch angle with different wing setups without the propeller motor. …”

Numerical study of trapped vortex combustors characteristics in small ramjets by Chen, Song

“…The results show that the optimal cavity size that traps a vortex inside can be determined by calculating the drag coefficient. Because the designed small combustor does not have bypass air directed into the cavity, injecting all the fuel directly in the optimal cavity always leads to an overly fuel-rich condition. …”

An experimental and simulation study of chip transportation behaviour in gundrilling by Tnay, Guan Leong

“…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. …”

Prediction of Intermittent Fluctuations from Surface Pressure Measurements on a Turbulent Airfoil by Rudy, Samuel H., Sapsis, Themistoklis P.

“…We show that methods using data-driven models of low order dynamic variables outperform those without dynamic models and that unlike previous works, low dimensional initializations do not accurately predict observables with extreme events such as drag.…”
