Numerical Modelling and Simulation of High Temperature Processes

Temperatur- und Strömungsverteilung in bioliq EFG — Temperature and flow field distribution in bioliq EFG

Validierung der numerischen Ergebnisse mit experimentellen Ergebnissen — Temperature and dry volume distribution in REGA at a burner distance of 680 mm and for two operating conditions including validation of two developed global reaction mechanisms for the gasification of ethylene glycol (HVI1 and eJL)

The Research on numerical modelling and simulation has become an important element for developing of validated models and for the design and the scale-up of reactors. In collaboration with the Institute for Technical Chemistry (ITC vgt) at Karlsruhe Institute for Technology and the Institute for Energy Process Engineering and Fuel Technology (IEVB) at Clausthal University of Technology, in particular, we are investigating and improving the description of sub-processes in entrained flow gasification :

vaporisation of liquid biomass fuels,
decomposition and heterogeneous gasification of both liquid and solid biomass fuels,
homogeneous gasification,
radiation,
slagging.

Using numerical models of an atmospheric entrained flow gasifier (REGA) and of a high-pressurised entrained flow gasifier (bioliq EFG), we are testing and validating new models for entrained flow gasification of biomass fuels.
