Flow Regimes and Föhn Types Characterize the Local Climate of Southern Patagonia
The local climate in Southern Patagonia is strongly influenced by the interaction between the topography and persistent westerlies, which can generate föhn events, dry and warm downslope winds.

An analysis of flow-like motion of avalanches based on physical modeling experiments
Flow-like motion is the main forms of rock avalanche emplacement, which is the foundation to reveal the dynamic mechanisms of rock avalanches. In this paper, a series of physical modeling experiments based on the Particle Image Velocimetry(PIV)analysis ...

H umans have long been fascinated by the dynamism of free-flowing waters. Yet we have expended great effort to tame rivers for transportation, water supply, flood control, agriculture, and power generation. It is now recognized that harnessing of streams and rivers comes at great cost: Many rivers no longer support socially valued native species or ...

Construction and Testing of a Rarefied Gas Flow Facility [PDF]
A low-density gasdynamic facility, suitable for measurement of mass flow through small (approximately 1 mm diameter) nozzles, tubes, and orifices, was designed and constructed. The system is capable of producing and measuring mass flows at 100:1 upstream/

A discriminative method to flow regimes based on the flow resistance law
Upper- and lower-flow regimes are formed under different conditions. To identify them is important for predicting mobile bed resistance. Based on the dimensionless resistance equation, a new discriminant function to flow regimes is deduced, which ...
