shock surface मीनिंग इन हिंदी

Air flowing in through the shock surface is trapped between the shock and the fuselage, and can only escape at the rear of the fuselage.
Though shock waves are sharp discontinuities, in numerical solutions of fluid flow with discontinuities ( shock wave, contact discontinuity or slip line ), the shock wave can be smoothed out by low-order numerical method ( due to numerical dissipation ) or there are spurious oscillations near shock surface by high-order numerical method ( due to Gibbs phenomena ).
