|Title:||Effect of inlet swirl and dump-gap on the wall pressure distribution of a model can-combustor|
Veeravalli, S V

|Abstract:||Wall static pressure distributions along the casing and liner wall have been measured using a Scanivalve digital manometer, for a model can-combustor under isothermal flow conditions for non-swirling and swirling flow at inlet with different positions of the liner (dump-gap). It is observed that swirl reduces the size of wall recirculation zone and permits earlier flow development whereas, dump-gap alters the reattachment length for weak swirling flows only. It is also observed that liner wall pressure (specially dome region) has a strong dependence on dump-gap for strong swirling flows due to formation of a central recirculation zone.|
