Inviscid flow Inviscid flow Inviscid flow is the flow of an inviscid fluid, in which the viscosity of the fluid is equal to zero. Though there are limited examples of inviscid fluids, known as superfluids, inviscid flow has many applications in fluid dynamics. The Reynolds number of inviscid flow approaches infinity as the viscosity approaches zero. When viscous forces are neglected, such as the case of inviscid flow, the Navier-Stokes equation can be simplified to a form known as the Euler equation. This simplified equation is applicable to inviscid flow as well as flow with low viscosity and a Reynolds number much
Memorial to the German Resistance the German resistance in the broader sense. Historians agree that there was no united, national resistance movement in Nazi Germany at any time during Hitler's years in power (1933–45). Joachim Fest describes it as "the resistance that never was." Nevertheless, the term German Resistance ("Deutscher Widerstand") is now used to describe all elements of opposition and resistance to the Nazi Regime, including the underground networks of the Social Democrats and Communists, The White Rose, opposition activities in the Christian churches (e.g. the Confessing Church), and the resistance groups based in the civil service, intelligence organs and armed forces.
