Numerical Study and Performance Verification of a Marine Liquid Fuel Volute Cyclone
摘要
Abstract
To achieve the reliable ignition of marine liquid fuel volute cyclone and improve the combustion stability and efficien-cy of volute cyclone ,using RNG k-εtwo-equation turbulence model to design a kind of volute cyclone which meets the special needs of ship using,and get the numerical simulation of the mist combustion process of this volute cyclone of specific dimension. It listed seven different sets of fuel inlet flow rate,and obtained the inner flow field and gas temperature and species concentration distribution of outlet.It analyzed and compared the impact of these 7 sets of fuel inlet flow rate upon the gas temperature and com-ponents of outlet of this volute cyclone of specific dimension,and got the optimum fuel inlet flow rate which met the needs of ship using.The calculation result provides theoretical basis for the design of volute cyclone.关键词
