Water compressibility effect is considered at movement of bodies with numbers M<1.5. The thermal equation of a condition and thermodynamic features of expansion and water compressions are analyzed at movement with ultrahigh speeds. The rule of recalculation of pressure factors is offered at a flow over a thin profile an incompressible liquid on their values at set number M before shock attachment. Unlike Prandtl-Glauerts rule the offered approach considers thermodynamic properties of a liquid. Features of shock formation compression are analyzed at supersonic movement of water. The example of calculation of a water flow over thin wedge at numbers M<1.5 is demonstrated. |
KEY WORDS: thin profile, pressure factors, shock compression |
