Computational fluid dynamics - closed projects
Selected closed projects of the last decade:
- Poly-dispersed bubbly flows in vertical pipes (Testsolver)
- Poly-dispersed bubbly flows in complex geometries
- Modelling and simulation on boiling processes in pressurized water reactors
- Modelling and simulation of boiling flows in modules with large vertical dimensions
- Modelling of churn-turbulent flows
- Bubble entrainment caused by a liquid jet
- CFD-model development and validation related to the transport, deposition and re-suspension of aerosol particles
- CFD simulation of fibre material transport in a PWR core under loss of coolant conditions
- Modelling and simulation of two-phase flows in bubble columns
- CFD models for two-phase flows Ceramic solid foam packing
- Flow maps and models for transient two-phase flows
- Investigations on wet instable foams
- Insulation debris transport phenomena in water flow
In close co-operation with the department of Experimental Thermal Fluid Dynamics the following projects aiming on the generation of experimental data for two-phase flows suitable for CFD code qualification were done:
- Gas-liquid flows in vertical pipes
- Flow around an obstacle in a vertical DN200 pipe
- Hot leg model of a Pressurized Water Reactor (PWR)
- Stratified flows
- Pressurized Thermal Shock (PTS) in case of Emergency Core Cooling in a PWR
- Experiments on boiling processes in pressurized water reactors
- Experiments related to the transport, deposition and re-suspension of aerosol particles
In addition there was a close cooperation with the department of Reactor Safety of the Institute of Resource Ecology in the field of CFD code development regarding:
- the analyses of boron dilution transients and
- the coupling of CFD with the reactor core model DYN3D.
