The critical Reynolds number (Rexcr) is a dimensionless parameter used in fluid dynamics to characterize the transition from laminar to turbulent flow over an object, such as an airfoil or a pipe. It represents a critical threshold at which the flow behavior changes from being relatively smooth and orderly (laminar) to becoming chaotic and turbulent.
