SovovaMulti.jl

Kinetic model fitting for supercritical fluid extraction.

Build Status Documentation Documentation

Overview

SovovaMulti.jl fits kinetic models for supercritical fluid extraction (SFE) to one or more experimental extraction curves. The package:

  • Accepts experimental data and operating conditions in laboratory units (g, cm, min).
  • Supports 8 kinetic models, from a rigorous PDE model to simple empirical correlations.
  • Fits model parameters using global optimization from BlackBoxOptim.jl — no manual multi-start needed.
  • Provides a graphical interface accessible via desktop shortcut or sovovagui().
