Temperature in isentropic flow over a wing refers to the change in temperature that occurs when air flows over the wing while maintaining an isentropic (constant entropy) process. Isentropic flow is a theoretical idealization where no energy is lost due to factors like friction, heat transfer, or shock waves. When air flows over an aircraft wing, it experiences changes in pressure, velocity, and temperature. The temperature change is influenced by the compression or expansion of the air as it moves from areas of higher pressure to lower pressure and vice versa.Â
- is the temperature at a specific point in the flow.
- is the free-stream temperature (ambient temperature at far upstream conditions).
- is the pressure at the specific point in the flow.
- is the free-stream pressure (ambient pressure at far upstream conditions).
- (gamma) is the specific heat ratio of the fluid (typically around 1.4 for air).
