Effect of Free Stall Pen Design on Feeding Behavior

American Association of Bovine Practitioners Conference Proceedings, 2005
The purpose of this study was to determine if a difference exists in group feeding behavior in dairy cows housed in free stall pens with either 2-rows or 3-rows of stalls.

Investigation on the Stall Inception Circumferential Position and Stall Process Behavior in a Centrifugal Compressor With Volute

Volume 2B: Turbomachinery, 2018
The present paper numerically and experimentally investigates the stall inception mechanisms in a centrifugal compressor with volute. Current studies about stall inception pay more attention on the axial compressors than the centrifugal compressors; especially, the circumferential position of stall inception onset and the stall process in the ...

Investigation of In-Stall Behavior in a Transonic Compressor Rotor

Volume 2D: Turbomachinery, 2017
This paper shows the results of three-dimensional multi-passage numerical simulations on a transonic compressor, NASA compressor Rotor 37. The aim is to investigate the unsteady flow on the stall condition and elucidate the dynamic evolution mechanism of the rotating stall.

The Effects of Reynolds Number on the Stall and Pre-Stall Behaviour of Compact Axial Compressors

Volume 2A: Turbomachinery, 2020
Abstract Compact axial compression systems are of interest to the domestic appliance industry. The associated low Reynolds number leads to high losses compared to large-scale compressors due to a transitional flow field with large regions of separation.

Factors affecting lying behavior and stall utilization of dairy cattle

Applied Animal Ethology, 1980
Abstract Intensive management of dairy cattle in free-stall housing during the dry period may impose unknown stresses. In this study, factors affecting laterality (side cow lies on), and stall usage under relatively uncrowded conditions by dairy animals in late pregnancy were evaluated. Fifty-nine dry Holstein cows and 18 heifers were observed during

Determinants of Undesirable Behaviors in American Quarter Horses Housed in Box Stalls

Journal of Equine Veterinary Science, 2019
The objective of this study was to investigate the management practices that affect undesirable behaviors in American Quarter Horses (AQH) confined to box stalls. A total of 105 adult AQH, comprising 29 females, 22 intact males, and 54 castrated males, housed in box stalls for at least 30 days, were included in the study.

CFD evaluation of the effects of stall control devices and transition tapes on stall behavior of airplanes

32nd AIAA Applied Aerodynamics Conference, 2014
Steady RANS results from low speed computational fluid dynamics studies of a business jet in flap-stowed and flap-deployed configurations are presented. Effects of leading edge transition trips on aerodynamic performance at and near stall conditions are investigated.

Application of CFD to explain stall behavior of the SSME flowmeter

35th Joint Propulsion Conference and Exhibit, 1999
1. Background of SSME Flowmeter Behavior Minor variations in the SSME’ fuel flowmeter constant (KJ during engine operation has been shown to be the result of wakes of the upstream hexagonal web flow straightener periodically partially stalling the rotor blades, thereby changing the lift on the blades and the rotation speed of the rotor. (This flowmeter
