| Abstract: | The pressure anisotropy within a shock layer results in an additional property of the shock wave: the surface tension. Its value amounts to 103 dyn/cm for Mach number 10. The surface tension term in the characteristic equation causes an absolute shock wave instability in the spontaneous sound emission regime. |
