Numerical Simulation of Effects of Gravity on the Micro Jet Flame in the Confined Space

Article Preview

Abstract:

A microscale ceramic tube was used as a burner jet, and a coaxial jet flame was established in the confined space between the ceramic tube and the outer quartz glass tube. The effects of gravity on the small jet flame characteristics in the confined space were investigated numerically. Comparisons between the experimental data and the numerical data showed that characteristics of the small jet flame structure and temperature field were in good agreement. It verified the accuracy of the numerical simulation. Numerical simulations of flame characteristics at zero gravity level were performed. The results show that the gravity level has a greater influence on the flame width than that on the flame length. The chemical reaction rate is larger under the condition of normal gravity than that of zero gravity.
