Unformatted text preview: 4.5 Bernoulli's integral for two types of steady, isentropic, compressible flows: (a) perfect gases and (b) liquids with constant compressibility. Isentropic expansion of a gas into vacuum. A criterion for “incompressible flow.” 4.6 The general form of Bernoulli's integral (for unsteady as well as steady flow). Examples: startup transients, Rayleigh bubble oscillation, etc., mainly in incompressible flows. 4.7 Introductory comments on potential (vorticity-free) flow and the velocity potential φ . Incompressible flows as solutions of ∇ 2 φ = 0 with ∂φ / ∂ n =0 at solid boundaries. The equation for pressure in terms of the velocity potential φ .
