Temperature ahead of the shock () refers to the temperature of a fluid at a specific location located upstream (before) of a shock wave in a compressible fluid flow. This temperature is the actual molecular temperature of the fluid at rest, measured before the fluid encounters the shock.
- Temperature behind the shock (T2) in K
- Ratio of the temperature behind shock to ahead of shock (T2/T1)
- Temperature ahead of shock (T1) in K
