VENT-II is a one dimensional nodal model, solving a reduced form of the Navier-Stokes equations and a semi-empirical condensation model at the interior flue surface. In addition to cycling and ambient conditions, boundary conditions at the appliance outlets characterize flue gas properties relative to user-defined cycling, temperature profiles, firing rates, and percentage of excess air.
