WebOct 5, 2024 · Crocco’s theorem shows that whenever an enthalpy or entropy gradient is present, the flow must be rotational. This explicitly confirms the equivalence between isentropy and irrotationality. The theorem is particularly important for transonic flow and supersonic/hypersonic blunt-body flow, where a shock wave either terminates a … WebCrocco is an Italian surname.

The resulting new relations hold for an unsteady, 3-D flow with body and viscous forces, heat … WebIt was established that the flow was essentially onedimensional with little curving of the flow tube only near the flame front. Entropy generation from vorticity was negligible when compared with the entropy produced from combustion of methane in oxygen, as it was determined through an application of Crocco’s theorem.
