Rex1 refers to the local Reynolds number associated with a specific region on an object, such as an airfoil or wing. The Reynolds number is a dimensionless quantity used in fluid dynamics to characterize the flow regime and predict the behavior of fluid flow around an object.
- Rex1: Local Reynolds number for a specific region (e.g., region 1)
- x1: Characteristic length of the specific region
- c: Chord length of the object
- Rec: Reynolds number based on the chord length
