  • The matching relationship between locations of air and fuel injection in cavities is one of the most important parameters of trapped-vortex combustor(TVC).Researches were conducted to evaluate seven groups of air and fuel parameters covering4 injection locations in cavities and 3 mixed air hole locations.The combustion performance test was performed under different injection temperatures and flow rates.So,the relationship among ignition performance,lean blow out(LBO) and efficiency,and 7 groups of air and fuel parameters was obtained,showing that the 7th parameter is an optimal parameter of air and fuel injection in cavities.
