Fluid mechanics researchers from Brown University and the University of Toulouse found that surfactants give the celebratory drink its stable and signature straight rise of bubbles.
A NEW MEAN VELOCITY SCALING FOR TURBULENT BOUNDARY LAYERS
TURBULENT BOUNDARY LAYERS MEAN VELOCITY SCALING
2014/12/30
A new scaling, originally developed for the mean velocity
profile of turbulent pipe flow, was extended to the case of zero
pressure gradient turbulent boundary layers. At low Reynolds
numbers, the ...
Investigation on a new method of adaptive drag reduction and nonablation thermal protection system for hypersonic vehicles
hypersonic drag reduction heat flux jet aerospike numerical simulation

A new adaptive drag reduction and nonablation thermal protection method named Telescopic Selfaligning JetSpike (TSAJS) is proposed to improve the conventional spiked method employed in hypersonic v...
On a new type of solitary surface waves in finite water depth
Solitary wave peaked crest progressive wave fully nonlinear
2012/4/24
In this paper, a new type of solitary surface waves in a finite water depth is found by analytically solving the fully nonlinear wave equations. Using a new type of base functions which decays exponen...
A new method of quality improvement for quadrilateral mesh based on small polygon reconnection
Mesh improvement Topological clean-up Quadrilateral mesh Small polygon reconnection
2012/2/24
In this paper, a new method of topological cleanup for quadrilateral mesh is presented. The method first selects a patch of mesh around an irregular node. It then seeks the best connection of the sele...
