Stagnation temperature

$$T_{0}=T+\frac{1}{2C_{P}}\vec{v}^{2}$$

$$\frac{T_{0}}{T}=1+\frac{\vec{v}^{2}}{2C_{P}T}$$

$$=1+\frac{1}{2}\frac{\vec{v}^{2}}{C_{P}}\frac{\gamma R}{\gamma R}$$

$$a^{2}=\gamma RT$$

 

$$=1+\frac{1}{2}\frac{\gamma R}{C_{P}}\frac{\vec{v}^{2}}{a^{2}}$$

$$M=\frac{\vec{v}}{\vec{a}}$$

$$=1+\frac{1}{2}\frac{\gamma R}{C_{P}} M^{2}$$

 

$$\frac{\gamma R}{C_{P}}$$

$$=\frac{\gamma (C_{P}-C_{v}}{C_{P}}$$

$$=\gamma\left(1-\frac{C_{v}}{C_{P}}\right)$$

$$=\gamma\left(1-\frac{1}{\gamma}\right)$$

$$=\gamma-1$$

 

 $$\frac{T_{0}}{T}=1+\frac{1}{2}(\gamma-1)M^{2}$$
