Turbulent snow transport and accumulation: New reduced‐order models and diagnostics
Quarterly Journal of the Royal Meteorological Society, EarlyView.Our new reduced‐order models of snow particle transport provide high‐fidelity calculations of snow accumulation in turbulent flows at significantly reduced computational costs. Additional accumulation diagnostics from the reduced‐order model predict complex patterns of particle concentration in turbulent boundary layers via coherent flow structures in ...

Upstream actuation for bluff-body wake control driven by a genetically inspired optimization
Journal of Fluid Mechanics, 2020 The control of bluff-body wakes for reduced drag and enhanced stability has traditionally relied on the so-called direct-wake control approach. By the use of actuators or passive devices, one can manipulate the aerodynamic loads that act on the rear of ...

Environmental Toxicology, EarlyView.ABSTRACT Freshwater turtles are valuable sentinels of aquatic systems due to their long lifespans and resilience in environments impacted by contaminants. The Permian Basin, dominated by the oil and gas sector, spans western Texas and southeastern New Mexico, USA, including the Pecos River and its tributaries, the Delaware and Black Rivers.

, 2020 The stable flame is vulnerable in the micro-scale combustors due to the significant heat loss and the limited residence. In this study, the bluff-body and cavity are integrated in a microchannel to enhance the combustion performance of premixed H2/air ...

‘A Sort of Armed Argument’: Ireland's Civil War of Words
History, EarlyView.Abstract This article sets out to contribute to the study of the languages of European civil wars through outlining and analysing the deployment of language as a weapon by the opposing sides of the Irish independence movement that split over the terms of the Anglo‐Irish Treaty of December 1921.

MATEC Web of Conferences, 2018 Vortex shedding from a bluff body results in fluctuating forces acting on the bluff body, which may induce vibration of the bluff body when the bluff body is elastically mounted or deformable.

Drag of a D-shaped bluff body under small amplitude harmonic actuation
Theoretical and Applied Mechanics Letters, 2015 Open-loop flow control method was used to affect the development of a turbulent wake behind a D-shaped bluff body. Loud speakers were embedded inside the bluff body to produce two zero-net-mass-flux jets through 2 mm-wide span-wise slots located along ...

Brook no compromise: How to negotiate a united front
American Journal of Political Science, EarlyView.Abstract Negotiating factional conflict is crucial to successful coordination: Political parties, rebel alliances, and authoritarian elites must all overcome internal disagreements to survive and achieve collective aims. Actors in these situations sometimes employ hardball tactics to block outcomes they dislike, but at the risk of causing coordination ...

Why did Putin invade Ukraine? A theory of degenerate autocracy
American Journal of Political Science, EarlyView.Abstract Many dictatorships end up with a series of disastrous decisions such as Hitler's attack on the Soviet Union or Saddam Hussein's aggression against Kuwait. Even if a certain policy choice is not ultimately fatal for the regime, such as Mao's Big Leap Forward or the Pol Pot's collectivization drive, they typically involve both a miscalculation ...
