Title Ramjet design and numerical simulation of the powder fuel

Abstract Powder fuel ramjet rocket engine as a new technology has been widespread concern in the various countries in related fields。Since the 1940s it was suggested that the relevant concepts, because of technical limitations and related disciplines are not perfect powder fuel ramjet has not been large-scale development。

Powder fuel ramjet is a simple, safe and efficient, easy to maintain new rocket engines。 This paper is pided into three parts powder fuel ramjet discussion。The first part of the engine fuel supply system design notes, as an important part of the supply system of the engine has an irreplaceable role。The second part of the ingredients for the selection and the best working environment and the powder fuel thermodynamic calculations were discussed and compared according to the results。The third part of the Fluent software engine inside the simulation, analysis of the designed engine under different air mass flow rate of the combustion chamber temperature, pressure, Mach number change and comparative analysis。

Keywords Fuel supply system Metal powder fuel thermodynamic calculation Fluent simulation
