Ratio of New and Old Temperature Solution

STEP 0: Pre-Calculation Summary

Formula Used

Temperature Ratio across Shock = (1+((Specific Heat Ratio-1)/2)*Normal Velocity/Old Speed of Sound)^(2)
Tshock_ratio = (1+((γ-1)/2)*V_n/c_old)^(2)
This formula uses 4 Variables

Variables Used

Temperature Ratio across Shock - Temperature ratio across shock is the ratio of downstream temperature to upstream temperature across the shock wave.
Specific Heat Ratio - Specific Heat Ratio of a gas is the ratio of the specific heat of the gas at a constant pressure to its specific heat at a constant volume.
Normal Velocity - (Measured in Meter per Second) - Normal velocity is the velocity normal to the shock formation.
Old Speed of Sound - (Measured in Meter per Second) - Old speed of sound is the speed of sound before the shock, it is used in the analysis of shock dynamics.

STEP 1: Convert Input(s) to Base Unit

Specific Heat Ratio: 1.6 --> No Conversion Required
Normal Velocity: 1000 Meter per Second --> 1000 Meter per Second No Conversion Required
Old Speed of Sound: 342 Meter per Second --> 342 Meter per Second No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

Tshock_ratio = (1+((γ-1)/2)*V_n/c_old)^(2) --> (1+((1.6-1)/2)*1000/342)^(2)

Evaluating ... ...

Tshock_ratio = 3.52385349338258

STEP 3: Convert Result to Output's Unit

3.52385349338258 --> No Conversion Required

FINAL ANSWER

3.52385349338258 ≈ 3.523853 <-- Temperature Ratio across 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
