“…There are two basic approaches, First, there is the use of some simple theory. So long as the flow is laminar, the predictions using the Svab-Zeldovich transformation are in good agreement with experimental results (60)(61)(62)(63)(64). These theories assume a heat of pyrolysis using the feedback energy as the pyrolysing mechanism.…”

“…A momentary reduction in the combustion rate, reported in theoretical works (Adomeit, et al, 1985;Makino & Law, 1986;Matsui & Tsuji, 1987;Henriksen, 1989;Makino, 1990;Makinoreactions. In spite of this theoretical accomplishment, there are very few experimental data that can support it.…”

“…Among previous studies (Tsuji & Matsui, 1976;Adomeit, et al, 1976;Adomeit, et al, 1985;Henriksen, et al, 1988;Matsui & Tsuji, 1987), it may be noted that Adomeit's group has made a great contribution by clarifying water-catalyzed CO-O 2 reaction (Adomeit, et al, 1976), conducting experimental comparisons (Adomeit, et al, 1985), and investigating ignition/extinction behavior (Henriksen, et al, 1988). Here, an extension of the worthwhile contributions is made along the following directions.…”

“…Although the cooling of solid surfaces by impinging air jets has been investigated extensively, such as the studies listed in References 8-11, uncertainty arises when these heat transfer results are used to estimate liquid vaporization rates because both heat and mass transfer are involved in the process. On the other hand, studies were performed to investigate the burning behavior of solid combustibles in stagnation flow fields [12][13][14][15]. Again, the uncertainty is high in deducing liquid vaporization rates in combustion-free stagnation flow fields from these burning rate results.…”

A theoretical model was developed to predict the flammable liquid vaporization rate from a heated pool subjected to impingement of a vertical air jet. The model divides the air flow field into two regions: one is the bulk air jet turning region and the other is the thin boundary layer formed on the liquid surface. The model is based on the premise that the thickness of the boundary layer in which vapor diffusion takes place above a liquid pool is mainly controlled by the impinging air jet. The model predicts that the liquid vaporization rate increases with the pool temperature and increases linearly with the impinging velocity, as opposed to the square-root dependence in the case of air flow parallel to the pool surface. The model was validated with vaporization rate data of high flash-point liquids. It is shown in this paper that the vapor blowing effect on boundary layer thickness greatly diminishes as the impinging air velocity increases from quiescence to 3.3 m/s for the high flash-point liquid pools analyzed in this study. The analysis also indicated that the boundary layer thickness on a small curbed pool could be greater than that predicted for an infinite pool. The resulting thicker fuel vapor diffusion layer tends to lead to lower vaporization rates than those expected from an infinite liquid pool under the same air impingement condition. KEYWORDS
