Three-Dimensional Unsteady Multi-stage Turbomachinery Simulations using the Harmonic Balance Technique
Three-Dimensional Unsteady Multi-stage Turbomachinery Simulations Harmonic Balance Technique
2015/7/2
In this paper, we propose an extension of the Harmonic Balance method for three dimensional, unsteady, multi-stage turbomachinery problems modeled by the Unsteady Reynolds-Averaged Navier-Stokes (URAN...
In tuning friction to the point where it disappears,technique could boost development of nanomachines
tuning friction to the point disappears nanomachines
2015/6/18
Friction is all around us, working against the motion of tires on pavement, the scrawl of a pen across paper, and even the flow of proteins through the bloodstream. Whenever two surfaces come in conta...
Researchers from North Carolina State University have developed a new processing technique that makes light emitting diodes (LEDs) brighter and more resilient by coating the semiconductor material gal...
Derivation of a second-order model for Reynolds stress using renormalization group analysis and the two-scale expansion technique
Turbulent modeling Renormalization group Two-scale expansion Reynolds stress transport equation Second-order model
2012/2/29
With the two-scale expansion technique proposed by Yoshizawa, the turbulent fluctuating field is expanded around the isotropic field. At a low-order two-scale expansion, applying the mode coupling app...
