Abstract

The invention provides a research method for the fuel oil liquid drop evaporation process in a porous medium model structure. The method includes the steps that Gambit software is used for constructing three model structures (including aligned arrangement and interleaved arrangement structure porous medium models instead of a porous medium model), corresponding grids are drawn, and wall surface attribute in the models as well as a fluid region and a solid region are set; grid files of the three kinds of models manufactured by Gambit are guided into Fluent software, and calculation method in the three models and the physical property parameters of fuel oil liquid drops are set by the Fluent software and calculated respectively, and then the fuel oil liquid drop evaporation processes in the three kinds of models are compared to obtain a mass fraction distribution cloud picture of the fuel oil liquid drops. The distribution rule of the mass fraction of the fuel oil liquid drops can be researched and analyzed, which is of great significance in further improving fuel combustion efficiency, reducing pollutant emission and researching and developing a new porous medium model.

Description

technical field [0001] The invention relates to the prediction and optimization of the diesel evaporation process in a porous medium stacked bed and a porous medium engine, in particular to a method for simulating, predicting and optimizing the droplet evaporation process in a porous medium model structure by using Fluent software. Background technique [0002] Combustion of fuel is the main way for human beings to obtain energy. More than 80% of the energy in the world today comes from the combustion of fossil fuels. How to reduce combustion emissions and improve combustion efficiency has become two hot topics in the current combustion field. For this reason, scholars at home and abroad have proposed various new combustion technologies. In the past two decades, porous media filtration combustion technology [MujeebuMA, Abdullah MZ, Abu Bakar MZ, et al, Journal of Environmental Management, 2009, 90: 2287-2312] has attracted academia’s attention due to its outstanding features...
