Recent Research Acitivities

In his current research, Franz Tanner focuses on the modeling and
computer simulation of turbulent, reacting multiphase flows with applications
to engines. The objectives of this research are the understanding
and description of the flow, spray and combustion phenomena involved, as
well as the determination of their influence on fuel efficiency, power
output and pollution formation. The long-term goal of this research is
the development of a versatile computational tool which can be used in
the design process of cleaner and more efficient combustion devices.
In this context Franz Tanner has developed various models, including
The Cascade Atomization and Drop Breakup (CAB) model, which is a further
development of his Enhanced Taylor Analogy Breakup (ETAB) model,
The Least-Square-Fitted Ignition Transport (LIT) model, which is a further
development of the earlier developed Simplified Kinetic Ignition (SKI)
model,
A non-equilibrium turbulence correction to the widely used RNG-k-epsilon
turbulence model (in collaboration with the Engine Research Center of the
University of Wisconsin-Madison)
Turbulence Scaling laws for the characteristic combustion time in diesel
Engines (in collaboration with the Engine Research Center of the University
of Wisconsin-Madison)
Future research will focus on the improvement of the solution algorithms
and the further development of the mathematical and physical descriptions
of the phase-transition phenomena, the turbulence model and the combustion-related
pollutant formation.
