The acoustic wave generation by a thin layer with variable temperature by Roman DYBA, Bronisław ŻÓŁTOGÓRSKI

“…This study considers the problem of the thermal sound generation in the air by an unmoving solid body with a time-variable temperature. Applying the linear relations between the thermal energy stream supplied to a thin layer of a solid body in touch with a gaseous medium and an energy stream of the acoustic wave, and then taking advantage of electrothermo-acoustic analogies, the phenomena of the energy transport were represented in the form of an equivalent linear electric circuit with lumped constants. …”
