摘要

尽管对液体燃料上的火焰蔓延进行了广泛研究，但在其控制机制方面仍存在一些尚未解决的问题。此外，最先进的模型并没有解决所有潜在的重要过程，如详细的化学过程，从而限制了预测的准确性。在本研究中，我们之前开发的全耦合三维数值方法扩展了多步骤化学过程。改进后的模型将用于研究不同燃料温度和熔池深度下的火焰蔓延情况，旨在揭示气体和液体流动特征的基本细节。

Computational analysis of flame spreads over alcohol fuel at sub-flash temperatures using multi-step chemistry

Although flame spread over liquid fuel has been extensively investigated, there still exist some unresolved issues on its controlling mechanisms. In addition, state-of-art models have not addressed all the potentially important processes such as detailed chemistry, limiting the prediction accuracy. In the present study, our previously developed fully coupled three-dimensional numerical approach is extended with a multi-step chemistry. The improved model is then used to investigate flame spreads under different fuel temperatures and pool depths, aiming to reveal fine details of the underlying gas and liquid flow features.

期刊介绍： Fire Safety Journal is the leading publication dealing with all aspects of fire safety engineering. Its scope is purposefully wide, as it is deemed important to encourage papers from all sources within this multidisciplinary subject, thus providing a forum for its further development as a distinct engineering discipline. This is an essential step towards gaining a status equal to that enjoyed by the other engineering disciplines.
