Detailed & reduced Solvers

• Stabilized the solver with an adaptative time step solver during ODEs integration
• Added a steady state tolerance to stop solver when steady state is reached for computational time optimization.
• Added axial dispersion model.
• Allowed the solver to load results from previous session.

Models

• Updated the single droplet velocity models
• Added a new function for the algorithm of Godfrey and Slater (1995) to automatically select the single droplet velocity model based on system physical properties.
• Added a flooding function in the detailed and reduced solver to follow entrainment of droplets in the column (flooding detection).
• Added and activated the oscillatory velocity model for the continuous phase.
• Fixed the equilibrium solute concentration formula.

• Added Kühni column to the PPBDesigner package.
• Added and activated a reduced solver for RDC and Kühni columns.
• Added a display of results in 3D graphs (droplet volume distribution and solute concentration distribution).
• Fixed display of results beneath the graphs in the view column profiles Tab.
• Added ‘’export raw data’’ feature to export the chemical system properties and PPBDesigner results.

• Added a correlation to estimate the droplet mean diameter in the inlet feed distribution section.
• Added display of important PPBDesigner results in DWSIM-Pro sidebar of the unit-operation.
• Fixed PPBDesigner Editor GUI issues.
• Speeded up the PPBDesigner GUI start.

• Implemented PPBDesigner in the DWSIM-Pro environment.
• Developed a web-based editor for PPBDesigner Unit Operation.
• Added RDC column as first L-L Extraction Column of the PPBDesigner package.
• Used a detailed solver.
