Organ‐Pipe Oscillations in a Burner with Deep Ports

摘要: Data are presented on acoustic oscillations produced by a burner using hexagonal bank of hypodermic tubes as deep ports. Most the tests were made with ethane fuel, but some run methane and propane, for comparison. Both diameter length combustion chamber varied.It was found that could be considered driver which forced slugs gas in ports to oscillate. Burning incremental pulses combustible mixture periodically issuing from furnished energy drive when burned phase oscillating component pressure chamber. The phasing depended time‐lag factor function velocity gases through space, similar dark between mean burning points, width space itself.The not only ceased there failure satisfy timing criterion, also upon approach either...
