Mach Wave behind Shock Solution

STEP 0: Pre-Calculation Summary

Formula Used

Mach Number behind Shock = (Freestream Velocity-Local Shock Velocity for Mach Wave)/Speed of Sound
M₂ = (V_∞-W_m)/c_s
This formula uses 4 Variables

Variables Used

Mach Number behind Shock - Mach Number behind Shock is the Mach number over the body after a shockwave has occurred.
Freestream Velocity - (Measured in Meter per Second) - The Freestream Velocity is the velocity of air far upstream of an aerodynamic body, that is before the body has a chance to deflect, slow down or compress the air.
Local Shock Velocity for Mach Wave - (Measured in Meter per Second) - Local shock velocity for Mach Wave is the shock velocity after the shock wave refer for the Mach wave.
Speed of Sound - (Measured in Meter per Second) - The Speed of Sound is defined as the dynamic propagation of sound waves.

STEP 1: Convert Input(s) to Base Unit

Freestream Velocity: 98 Meter per Second --> 98 Meter per Second No Conversion Required
Local Shock Velocity for Mach Wave: 92 Meter per Second --> 92 Meter per Second No Conversion Required
Speed of Sound: 343 Meter per Second --> 343 Meter per Second No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

M₂ = (V_∞-W_m)/c_s --> (98-92)/343

Evaluating ... ...

M₂ = 0.0174927113702624

STEP 3: Convert Result to Output's Unit

0.0174927113702624 --> No Conversion Required

FINAL ANSWER

0.0174927113702624 ≈ 0.017493 <-- Mach Number behind Shock

Grid Point Calculation for Shock Waves

Go Grid Points = (Distance from X-Axis-Body Shape in Hypersonic Flow)/Local Shock-Detachment Distance

Mach Wave behind Shock

Go Mach Number behind Shock = (Freestream Velocity-Local Shock Velocity for Mach Wave)/Speed of Sound

Local Shock Velocity Equation

Go Local Shock Velocity = Speed of Sound*(Mach Number-Mach Number ahead of Shock)

Mach Wave behind Shock with Mach Infinity

Go Mach Number ahead of Shock = Mach Number-Local Shock Velocity/Speed of Sound

Mach Wave behind Shock Formula

Mach Number behind Shock = (Freestream Velocity-Local Shock Velocity for Mach Wave)/Speed of Sound
M₂ = (V_∞-W_m)/c_s

Wat is Shock Wave?

Shock wave, strong pressure wave in any elastic medium such as air, water, or a solid substance, produced by supersonic aircraft, explosions, lightning, or other phenomena that create violent changes in pressure

How to Calculate Mach Wave behind Shock?

Mach Wave behind Shock calculator uses Mach Number behind Shock = (Freestream Velocity-Local Shock Velocity for Mach Wave)/Speed of Sound to calculate the Mach Number behind Shock, The Mach Wave behind Shock formula is defined as a measure of the shock wave that forms behind an object moving at supersonic speeds, typically in hypersonic inviscid flow, where the shock wave is a compression wave that propagates through the fluid at a speed greater than the speed of sound. Mach Number behind Shock is denoted by M₂ symbol.

How to calculate Mach Wave behind Shock using this online calculator? To use this online calculator for Mach Wave behind Shock, enter Freestream Velocity (V_∞), Local Shock Velocity for Mach Wave (W_m) & Speed of Sound (c_s) and hit the calculate button. Here is how the Mach Wave behind Shock calculation can be explained with given input values -> 0.017493 = (98-92)/343.
