OpenQBMM 2.0.0 is now available! A list of the major changes follows.
- A general framework for the solution of evolution equations involving a distribution function was implemented (univariatePDFTransportModel).
- Turbulent mixing models: a new solver, mixingTransportFoam, is provided to solve turbulent mixing models using velocity fields obtained from RANS flows solvers. The following mixing models are available:
- EQMOM – IEM
- EQMOM – Fokker-Planck
- Moment advection fluxes were completely re-implemented, and based on the Gauss-Radau quadrature, improving stability and leading to a slightly lower computational cost. This framework allows high-order realizable schemes to be accommodated.
- The EQMOM procedure was generalized to support the beta kernel density function, allowing to manage problems involving NDF with support over [0, 1].
- The moment inversion algorithm implemented in the univariateMomentSet was extended
- The moment realizability test was extended to manage moments of measures defined on compact supports
- The N+1 nodes Gauss-Radau quadrature was implemented as alternative to standard N-nodes Gauss quadrature
- Multivariate moment inversion (CQMOM) was implemented.
- Growth models are now available in the population balance equation solver (external contribution).
- Validation cases for the population balance solvers were added to the validation suite, demonstrating the application of the method to problems involving aggregation and breakup in Taylor-Couette reactors.
