Abstract

ABSTRACT
This lecture describes recent numerical and experimental studies of Computational
Fluid Dynamics (CFD) and combustion in practical applications. The studies have
been performed in a range of laboratory platforms where controlled flow and
combustion take place. The lecture will cover a wide range of practical industrial
applications including burners’ swirl flames, premixed and non-premixed combustion,
internal combustion engines, fuel cells, hydrogen utilization and applications, dust
and hydrogen safety studies.
The numerical approaches used in the above studies range from simple ones that
are numerically feasible for practical applications such as those based on Reynolds
Averaged Navier-Stokes (RANS) equations to complex and numerically very
expensive such as Large Eddy Simulation (LES) methods. Experimentally, high
speed images of flow and combustion processes as well pressure-time traces are
widely available for a range of experimental conditions but flow field measurements
are less common due to the seeding difficulty associated with such transient
processes. This lecture will also review recent experiments where the flame front was
imaged using Laser Induced Fluorescence (LIF) from the hydroxyl radical of the
combustion process.
