  1. Flow at high Re Inviscid Flow Euler’s equation 0

  2. Euler’s equation Can use the vector identity:

  3. Can use the vector identity: alternate form of Euler’s equation

  4. 2 1 Look at component along a streamline irrotational flow

  5. For steady and irrotational flow : Bernoulli’s equation Bis constant everywhere

  6. For unsteady and irrotational flow, we get another form of Bernoulli’s equation For irrotational flows, the velocity vector can be written as: The gradient of a scalar potential – the velocity potential Inserting the velocity potential in:
