 Displacement-ventilation interface height

ID: displacement-ventilation-interface-height

At steady state, the displacement-ventilation interface lies where the total plume volume flux equals the imposed ventilation flux. For one triangular-profile wall line plume with kinematic buoyancy flux

B_{0}

α

, and ventilation flux

A

per unit span,

h = (\frac{2}{3 α})^{2/3} \frac{A}{B _{0}^{1/3}} .
