Connellsville Career & Technical Center’s heavy equipment program has a new learning tool to help students develop their skills. Thanks to a portion of a $250,000 Schools to Work Grant, the students ...

A numerical model to study the aerodynamic and aeroelastic bridge deck behavior is presented in this paper. The flow around a rigid fixed bridge cross-section, as well as the flow around the same ...

In yet another sign that winter weather is either here or will be soon, the dreaded polar vortex is making news yet again. Its potential arrival in the United States over the next few weeks is cause ...

High above the North Pole, in a slice of atmosphere rarely noticed and even less understood, a transformation is underway. Over the next 10 days, changes in the stratosphere will upend weather ...

In an early sign of the winter weather that's coming, the dreaded polar vortex is making news yet again. The polar vortex is "ramping up from its summer slumber," said meteorologist Judah Cohen in an ...

Abstract: In order to study the interaction of vortex structure,vortex evolution and vortex in a tubular turbine,the regularized helicity, Q-criterion and BVF diagnosis based on RNG k -ε turbulence ...

Tornadoes have caused severe disasters around the world, and have been one of the most violent and damaging natural hazards to human life and property. Experimental simulation of tornado-like vortices ...

Abstract: We implemented a simulation of vortex electromagnetic (EM) waves imaging for underwater targets. Depending on the approximate duality relationships between the topological charge of orbital ...
