This paper reports development of a two-dimensional solver for compressible viscous flow using spectral difference (SD) method and its applications on simulating laminar flow past two side...
Design-Oriented Aerodynamic Analysis for Supersonic Laminar Flow Wings
Super sound pneumatic
2015/6/18
The computation of boundary layer properties and
laminar-to-turbulent transition location is a very
complex problem, generally not undertaken in the
context of aircraft design. Yet if an aircraft i...

algae swimming microorganisms Taylor dispersion DNS turbulent transport bioreactors
2012/5/31
Algal swimming is often biased by environmental cues, e.g. gravitational and viscous torques drive cells towards downwelling fluid (gyrotaxis). In view of biotechnological applications, it is importan...
Absolute linear instability in laminar and turbulent gas/liquid two-layer channel flow
