Characteristics of thermal explosions on Newtonian and non-Newtonian fluids

An analytical study of thermal explosion on Newtonian and non-Newtonian fluid is carried out. Approximate solutions to the governing equations and analysis of the study in the Newtonian case, showed that an increase in Frank-Kamenestkii parameter and that of the Semenov parameter decreases the minimum temperature of the reacting fluid thereby delaying the initiation of thermal explosions while additional heat source brings about early initiation of thermal explosions. The same observation was deduced in the non-Newtonian case but in varying degrees.
