Experimental Investigation Into The Effects Of Thermal Recuperation On The Combustion Characteristics Of A Non-Premixed Meso-Scale Vortex Combustor, Seyed Ehsan Hosseini, Evan Owens, John Krohn, James Leylek

Faculty Publications - Mechanical Engineering

In small-scale combustors, the ratio of area to the combustor volume increases and hence heat loss from the combustor’s wall is significantly enhanced and flame quenching occurs. To solve this problem, non-premixed vortex flow is employed to stabilize flames in a meso-scale combustion chamber to generate small-scale power or thrust for propulsion systems. In this experimental investigation, the effects of thermal recuperation on the characteristics of asymmetric non-premixed vortex combustion are studied. The exhaust gases temperature, emissions and the combustor wall temperature are measured to evaluate thermal and emitter efficiencies. The results illustrate that in both combustors (with/without thermal recuperator), …
