Modeling of thermo- and fluid-dynamic processes during depressurisation of chemical reactors
Topics
- Development of the one-dimensional transient model BRICK for multiphase vessel flow
- Analysis, simulation and experiments investigating pulsations of the mass flow rate during depressurisation of reactors
- Small scale blow-down experiments with thermal induced decomposition of hydrogen peroxide
- Integration of foam models into one-dimensional transport codes
