This paper presents the thermodynamic study of valveless pulsed combustor when fuelled with propane gas. Methodology for evaluating the exergy performance was developed using the mass, energy and exergy balance between the input and output material streams in the combustor at ambient temperature. At three different consumption rates of fuel and air, the highest exergy efficiency of 65.61 % was obtained at the combustion chamber at 0.0013 kg/s of propane gas neglecting heat losses at the
