The design and performance of a high temperature rise combustor for wind tunnel

A high-temperature-rise combustor that can be used in high-temperature wind tunnel is introduced in this study. Aviation kerosene is used in this type of combustor, with division combustion scheme and evaporator fuel-supply device adopted. In the performance test under atmospheric pressure, when the inlet temperature is 500K and air flow is within the range of 1.5-3.0 kg/s, the outlet temperature can be precisely regulated within the range of 1050K-2100K. Moreover, higher uniformity of outlet temperature distribution and higher combustion efficiency can be achieved. After the long-time working in the wind tunnel, various components of the combustor, especially the combustor liners are checked without finding any anomaly such as thermal deformation.
