摘要:
It is analysed theoretically how the stirring of an exothermically reacting fluid layer affects its thermal explosion limits. Analytical and numerical analyses reveal that, in accordance with the intuitive expectations, the short-scale stirring makes the thermal explosion more difficult through the increased heat transfer to the boundaries. However, under the long-scale stirring, promoting formation of hot spots, transition to the explosion may be facilitated rather than hampered.
