[交流] fluent 非预混燃烧模拟是否考虑了煤粉水分

一直很疑问这个问题，fluent中都是用干燥无灰定义的，那fluent模拟时还会考虑煤粉水分的变化吗，换句话说，模拟烟煤和褐煤能区分吗，希望各位虫友积极发言

看fluent帮助文件：
Moisture in the coal can be considered by adding it in the fuel composition as liquid
water, H2O(l). The moisture can also be dened as water vapor, H2O, provided
that the corresponding latent heat is included in the discrete phase material inputs
in FLUENT. If the liquid water is used as a boundary species, it should be removed
from the list of excluded species (see Section 15.10.1: Forcing the Exclusion and
Inclusion of Equilibrium Species).
i Note that if water is included in the coal, the water release is not modeled
as evaporation, which is typically the case in the wet combustion model,
described in Section 22.12.2: Particle Types.
