Determination of the stability limit of a thermoacoustic engine by means of finite elements [PDF]

, 2013
A finite element model is presented to obtain the stability limit of, as an example, 2D standing wave thermoacoustic engine. The stability limit is the required heating to obtain self-sustained (thermo)acoustic oscillations. The method used to obtain the
