Effects of asymmetric and radial multi jets on the combustion and heat transfer characteristics in a divided chamber combustor are examined by measuring pressure histories and visualizing flow patterns in the main chamber. Diameter and arrangement of 40 nozzles, uniformly equipped on a hemi-circular sub-chamber, are varied in the manner that multiple radial jets produce various types of flow patterns in the main chamber before the main chamber mixture ignites. To examine the combustion characteristics pressure histories in the combustor are measured, whereas visualization of model water flows induced by the asymmetric multi jets is made to obtain flow characteristics before ignition. Based on the results obtained, the interrelation between the flow pattern and the combustion and heat transfer properties are considered and some key factors will be examined to introduce intense asymmetric flow fields in the divided chamber combustor.
