Abstract

A numerical study on n-heptane and air premixed combustion inside a micro tube is undertaken to investigate. The simulation result shows that the flame location moves towards downstream as the fuel mass rate improves and the rate of location and mass rate is K_T=x/m_f=14.22m s/g, the product of temperature slope and mass rate is P_t=S_t m_f =10.43K g/m s. With equivalence ratio's increasing, the flame moves upstream when mass rate is constant and temperature drops slowly first and then rapidly. The equivalence ratio can cut the combustion efficiency. A bigger heat loss rate h can make the temperature go down faster and cut the peak temperature a little.
