CORMIX1: Single Port Discharges

CORMIX1 predicts the geometry and dilution characteristics of the effluent flow resulting from a single port diffuser discharge, of arbitrary density (positively, neutrally, or negatively buoyant) and arbitrary location and geometry, into an ambient receiving water body that may be stagnant or flowing and have ambient density stratification of different types.

Submerged Single-Port Discharge
Submerged single-port discharge creates turbulent buoyant jet mixing in a stagnant ambient.

Additional Source Characterization Assumptions

  • All subsystems require that the actual cross-section of the water body be described or schematized as a rectangular straight uniform channel that may be bounded laterally or unbounded. The ambient velocity is assumed to be uniform within that cross-section.
  • In addition to a uniform ambient density possibility, CORMIX1 allows for three generic types of ambient stratification profiles to be used for the approximation of the actual vertical density distribution.
  • All CORMIX subsystems are in principle steady-state models, however new developments allow the analysis of unsteady mixing in tidal environments.
  • All CORMIX systems can predict mixing for both conservative and non-conservative first-order decay processes, and can simulate heat transfer from thermal plumes.
