5. Basics of acceleration phenomena

5.1 Isothermal flow in a pipe of variable cross-section

Assuming, to simplify the problem, that we have a homogeneous suspension of bubbles in a duct of variable cross-section S (x ), and that the global slip Γ is 1, the theorems of conservation of mass and momentum can be written in simplified form:

ρu S = Cte ^( 32 )

\frac{1}{S} \frac{d}{d x} (ρ u^{2}
