The temperature within a wind tunnel duct refers to the thermal state of the fluid or gas as it flows through the confined passage of the wind tunnel. It represents the average kinetic energy of the molecules that make up the fluid or gas. Changes in pressure due to the shape and design of the wind tunnel can lead to changes in temperature through processes such as compression (increase in pressure) or expansion (decrease in pressure).
- T1: Initial temperature at a specific point in the wind tunnel.
- T2: Temperature at the same fluid particle after it has undergone a change in pressure (compression or expansion).
- p1: Initial pressure at that specific point.
- p2: Pressure at the same fluid particle after the change.
- 𝛾: Specific heat ratio
