The influence of system parameters such as heater power and heater location on the hysteresis characteristics of a horizontal Rijke tube is studied in this paper. It is observed that the hysteresis zone is present for all the mass flow rates considered in the present study. The nature of transition to instability in a horizontal Rijke tube is found to be subcritical, in the range that we tested. A decrease in instability amplitude along with a reduction in the width of the hysteresis zone is observed in the presence of external noise. Period-2 oscillations are found when heater location is chosen as the control parameter
