通过跟踪引燃过程中化学反应激发区域的发展,以其扩展中由量变到质变的转折态,作为表征引燃的判据。以此分析了炽热平板层流边界层内可燃气流的引燃,给出了描述引燃的着火临界条件。在<二>中讨论了湍流混合区内高温已燃气对其可燃气流的引燃问题。这种模型,提供了统一处理各类工程引燃问题的可能。 By tracking the development of chemical reactions in the ignition process, the transition state from quantitative to qualitative change is used as a criterion to characterize ignition. Based on this, the ignition of the combustible gas flow in the boundary layer of the hot laminar flow is analyzed, and the critical condition of igniting ignition is given. In <2> discusses the turbulent mixing zone of high temperature gas has been ignited its combustible gas flow ignition problems. This model provides the potential for uniform handling of all types of engineering ignition problems.
