The pulsations and energy transfers in a double-orifice combustor

Beale, C. K. (1945) The pulsations and energy transfers in a double-orifice combustor. Doctoral thesis, Durham University.



This work examines the effect of longitudinal oscillations on the heat transfer in a naturally-aspirating, propane-fuelled combustor. Previous investigations in the field have been predominantly experimental in nature, although theoretical studies of the effect of oscillations on local heat transfer coefficients have been made. In this work, a linearised wave equation, which governs the propagation of sound waves in a gas confined by a straight tube and exhibiting an axial temperature variation, is used to correlate local heat transfer coefficients by a quasi-steady-state method. An apparatus was . constructed, and measurements of the gas, wall and water temperatures and of the gas pressure amplitudes were taken in a concentric tube heat exchanger, which formed part of the resonating section.
