Краткое описание

This paper presents some results on the numerical simulation of the two phase flow in a Lean Premixer Prevaporizer module. Several physical models concerning the liquid phase, validated on basic configurations, have been used. Droplet turbulent dispersion, evaporation, secondary break-up, as well as droplet-wall interactions and interactions between the liquid and gas phases are modeled. The two studied operating conditions (one with low pressure and temperature, the other with realistic ones) of the module have led to several conclusions. First of all, the ability of the code to simulate this kind of flows is demonstrated. Furthermore, the effect of the liquid phase on the gas phase is not negligible, especially near the wall in the first case studied, and near the injection point in the second case. Secondary breakup is also crucial, especially in the second case. However, some limitations have been pointed out. The liquid film behavior is a very important physical process, which has to be modeled more precisely to take into account its significant influence on the gas flow. Secondary break-up has to be implemented in the coupled version of the code. Some further developments are currently performed, leading to a more accurate numerical code.
