Abstract
Bluff bodies are common method used as flame holders or stabilizers in many applications such as jet
engines augmenters for reasons of safety, providing excellent turbulent mixing characteristics,
improvement in flame stability, and ease of combustion control.
The effects of using 12 different bluff body shapes (cylindrical and triangular with different
dimensions) are examined with respect to their influence on downstream flow field. The present work
offers a study to compare different bluff body geometries and their effect on the flame characteristics
and its stability using two main techniques; Experimental measurements using visualization and
Langmuir probe techniques and simulation technique using CFD method.
