Conflow: A numerical program for conduit flow and thermodynamics

by Larry G. Mastin (U.S. Geological Survey) and Mark S. Ghiorso (University of Washington)

The program Conflow calculates flow properties in eruptive conduits as well as thermodynamic, physical, and solubility properties of melts and melt-gas-crystal mixtures.  The input properties of the melt are illustrated below.
