2.5 Sound Speed in Two Phase Medium

For flow of mostly gas with drops of the other phase (liquid or solid)


$\displaystyle {\rho \over \rho_a} = 1 + m$ (8)

where $ m = {\dot{m}_b \over \dot{m}_a}$ is mass flow rate per gas flow rate. and the subscript a is for the gas phase and b for the liquid or solid phase.

The equation of state is

$\displaystyle {P \over \rho} = { R \over 1 + m} T$ (9)


and $ R_{mix} = { R \over 1 + m}$
