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. …”

An assimilation of experience. by Mehraj Nisha.

“…This inspired me to confront my biggest problem which is the class and social struggles still evident in India. I believe the fight for equality is going to a long one and till then people are going to struggle and miseries that are silenced are slowly going to want to break out and be addressed.…”

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. …”

Determination of operating point for a propulsive wing UAV using CFD by Chan, Chee Shuan

“…CFD simulations were performed using a 2D RANS k-ε turbulence model and the rotating flow was captured using the moving reference frame method. Lift and drag were obtained for different angle of attacks via a control volume analysis of CFD results. …”
