Effect of radiation on the critical Frank – Kamenetskii parameter of thermal ignition in a combustible gas containing fuel droplets.

Abstract




We investigate the effect radiation on the critical Frank-Kamenetskii parameter of thermal ignition in a combustible gas containing fuel droplets (furnaces, gas turbines and internal combustion engines). Previous works show that radiation delays ignition in a well stirred reactor. In this paper we show that, even in a non-homogeneous reaction, the critical Frank-Kemenetskii parameter increases as the radiation parameter increases when the activation energy is high. This confirms the experimented observation in diesel engines.
