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. …”

Active control of wakes and vortex-induced vibration of a circular cylinder at Re = 100 by Wang, Chenglei

“…As zero net-mass-flux jets, SJs have been widely applied in flow separation control and drag reduction for bluff bodies. However, their implementation for VIV control is rare and still remains not fully understood. …”

Why travel far to learn? A study of environmental behaviour change experience of residential outdoor environmental education participants by Syed-Abdullah, Sharifah Intan Sharina

Black hole binary formation and mergers in supermassive black hole discs by Rowan, C

“…</p> <p>Here, hydrodynamical simulations are performed of BH-BH interactions in AGN discs, showing that the energy of such encounters can be efficiently dissipated by the surrounding gas through a combination of accretion and gravitational drag, leaving behind a bound binary BH system (BBH). …”

Small towing tank for accurate testing of significantly scaled-down ship models by Chung, Hau Kim.

“…The computation results are compared against towing tank data in term of surface flow pattern, mean velocity field and drag. The results show that both two equation models k-ε and k-w provided commendable agreement with experimental data. …”

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.…”

Electrospinning pure protein solutions in core-shell fibers by Tiwari, Sandeep Kumar, Venkatraman, Subbu S.

“…However, the limitation of loading capacity still remains due the prerequisite of using an additional polymer as additive to achieve the minimum viscosity of the core solution required for viscous drag by the shell solution being drawn by the electrostatic force. …”
