Development of DragGAN application for photographers by Takesawa, Saori

“…This intuitive functionality not only streamlines the editing process but also eliminates the need for extensive image manipulation skills, catering to photographers of all proficiency levels. However, the technical intricacies and terminology of DragGAN limits its accessibility to users familiar with the AI field, posing barriers of its adoption among the photography community. …”

Computation fluid dynamics on drag reduction II by Zang, Bin

“…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 by Shen, Lian, Zhang, Xiang, Yue, Dick K.P., Triantafyllou, Michael S.

“…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. …”

Experimental investigation of a distributed propulsion system by Mehta, Ronak Chittesh

“…Another configuration was also tested, with an opposite rotation direction of the propellers, with similar parameters and showed an overall better performance than the prior configuration through higher lift and lower drag at all parameters resulting in a higher aerodynamic efficiency.…”

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. …”
