| 1. | However, potential flows also have been used to describe compressible flows.
|
| 2. | In compressible flow, however, the gas density and temperature also become variables.
|
| 3. | In fact, thermodynamics is typical of compressible flows and degenerates in incompressible flows.
|
| 4. | Compressible flow is responsible for these changes in pressure, velocity, density, and temperature.
|
| 5. | Inviscid compressible flow over slender bodies is governed by linearized compressible small-disturbance potential equation:
|
| 6. | There are also gravity currents with large density variations-the so-called low Mach number compressible flows.
|
| 7. | For an extensive list of compressible flow equations, etc ., refer to NACA Report 1135 ( 1953 ).
|
| 8. | Analyzing ducts flowing at higher velocities with mach numbers in excess of 0.3 usually require Compressible flow relations.
|
| 9. | In 1757, Leonhard Euler published the Euler equations, extending Bernoulli's principle to the compressible flow regime.
|
| 10. | More advanced forms may be applied to compressible flows at higher Mach numbers ( see the derivations of the Bernoulli equation ).
