Abstract
A flame tube of length 720 mm and diameter 100mm was used in an experimental investigation to examine the role of the secondary air holes on the performance of a can type combustion chamber. The flame tube is provided with an outer shell allowing annular area for the secondary air flow. The primary air flows through a swirler mounted on the inlet of the flame tube and which has a concentric jet for hot air flow simulating the fuel flow.
A temperature tracer technique was adopted at various locations across and along the flame tube to obtain the average concentration of the hot air in the mixture of hot and cold air streams. The average axial velocity distribution was obtained by means of two holes velocity probe.
The effect of variation of mass ratio of the primary air to the hot air (X), the diameter of the hot air nozzle. The outer shell diameter and of the configurations of the secondary air holes comprising: the position of the first row, the number of rows, hole diameter, and both the circumferential and axial pitch was analysed.
