An analysis of unsteady airfoil stall and stall flutter is presented that is based on a series of approximations. Unsteady aerodynamic characteristics are related theoretically to static aerodynamic characteristics. Preliminary results show good agreement with experimental dynamic stall data.

Evolution Process of Diffuser Stall in a Centrifugal Compressor With Vaned Diffuser
Journal of turbomachinery, 2018This paper describes in detailed flow field in a centrifugal compressor with a vaned diffuser at off design point. Especially, we conducted both the experimental and numerical analysis in order to investigate the evolution process of a diffuser stall. At

Free Stall Design Affects Stall Cleanliness
Livestock Environment VIII, 31 August - 4 September 2008, Iguassu Falls, Brazil, 2008The objective of this study was to describe typical free stall design in Norway and to evaluate the effect of free stall design on free stall cleanliness. In 232 Norwegian free-stalled dairy herds, trained observers scored cleanliness for 15 random stalls in each herd. The cubicle floor was divided into 7 sectors and the cleanliness of each sector were

This is the fifth occasion on which I have had the honour to address our Society and the third time I have chosen to discuss the same subject: “The stalling of aeroplanes.” I should apologise for thus harping upon a single string were it not that no subject could be more appropriate to an address in memory of Wilbur Wright, and were it not that until ...

Airfoil Drag Calculations in Stall and Post-stall Conditions
43rd AIAA Aerospace Sciences Meeting and Exhibit, 2005Numerical solutions of the Reynolds Averaged Navier-Stokes equations around airfoils in stall and post-stall conditions are proposed and post-processed by a drag analysis method, developed for applications in cruise and near-cruise conditions. The possibility to neglect Reynolds stresses in the wake when massive separations are present is discussed ...

Chapter 2 details the landscape surrounding domestic violence, highlighting its contradictions. On the one hand, women face a number of social, cultural, and institutional barriers to rights. Social stigma and limited access to housing and jobs constrain their options outside abusive relationships. Law enforcement personnel are overburdened and sexist,

This chapter relates how CBS Cinema Center Films agreed to make Two-Lane Blacktop and Monte Hellman chose cinematographer Gregory Sandor to shoot the film using wide-screen Techniscope. Over the objections of casting director Fred Roos, who brought in dozens of young, trained actors, Hellman chose rock stars for the two lead roles.: James Taylor, then ...

Structural Biology A small percentage of bacterial mRNAs lack a stop codon. Ribosomes stall at the end of such mRNAs, and the buildup of stalled ribosomes can be lethal. The primary rescue mechanism, in which translation continues on a piece of RNA that contains a stop codon, is a drug target. However, bacteria have another backup plan.
