Total temperature, denoted as is a thermodynamic property used in fluid dynamics and aerodynamics to describe the sum of the static temperature and the kinetic energy per unit mass of a fluid flow. It represents the total energy content of a fluid stream, including both its internal thermal energy and the energy associated with its motion.
- is the total temperature (in kelvin, K).
- is the static temperature (in kelvin, K) of the fluid.
- is the velocity of the fluid (in meters per second, m/s).
- is the specific heat capacity at constant pressure of the fluid (in joules per kilogram per kelvin, J/(kg·K)).
