Abstract
The main objectives of this investigation are the visualisation of the flame propagation depending on different boundary conditions. Turbulence intensities, wall-temperatures and an air-fuel ratios were varied in a wide range.
For the experiments a rapid compression machine with a quadratic piston and a good optical access is used which allows to observe the entire burning.
With an additionally integrated turbulence generator it is possible to create a defined turbulence field in the burning chamber.
