Numerical Study of the L/D Ratio and Turbulent Prandtl Number Effect on Energy Separation in a Counter-Flow Vortex Tube [PDF]
Journal of Applied Fluid Mechanics, 2022 Vortex tube is a device without moving parts with ability to separate pressurized gas into two streams: cold and hot. This is a consequence of the Eckert-Wiese effect, which is responsible for spontaneous redistribution of total energy within the flow ...

Unsteady stagnation point flow of a non-Newtonian second-grade fluid
International Journal of Mathematics and Mathematical Sciences, 2003 The unsteady two-dimensional flow of a viscoelastic second-grade fluid impinging on an infinite plate is considered. The plate is making harmonic oscillations in its own plane.

On the Circulation and the Position of the Forward Stagnation Point on Airfoils [PDF]
International Journal of Mechanical Engineering Education, 2007 Lift and velocity circulation around airfoils are two aspects of the same phenomenon when airfoils are not stalled and the Kutta—Joukowski theorem applies. This theorem establishes a linear dependence between lift and circulation, which breaks when stalling occurs. As the angle of attack increases beyond this point, the circulation vanishes.
