Aerodynamics Practice Test: Crocco's Theorem — Flashcards

Crocco's theorem is an aerodynamic theorem that relates the flow velocity, vorticity, and stagnation pressure of a potential flow. It also relates the thermodynamics and fluid kinematics. 

Crocco's theorem also relates the gradients of total enthalpy, gradients of entropy, and flow rotation. When a steady flow field has gradients of total enthalpy and/or entropy, Crocco's theorem shows that it is rotational. 
Crocco's theorem implies that the gradient of entropy contributes to the induction of circulation, and in consequence to the induction of lift.
