1. In practice, an inviscid flow is an laminar boundary layer. 2. The approximations to these problems are called inviscid flows. 3. The Prandtl Glauert transformation is a linearized approximation of compressible, inviscid potential flow. 4. Imposing the Kutta condition in the inviscid case is equivalent to creating a circulation. 5. Thus, high Reynolds number flows are approximately inviscid in the free-stream. 6. Helmholtz s theorems apply to inviscid flows. 7. These approximations are called inviscid flows. 8. Inviscid compressible flow over slender bodies is governed by linearized compressible small-disturbance potential equation:9. The relationship described by Bernoulli was found to be valid only for incompressible, inviscid flow. 10. These are governed by the Orr Sommerfeld equation for Rayleigh's equation for inviscid flow.
