molecular weight of gas的意思|示意

Natural gas in wellbore is a mixed gas consisting of various gas. Due to molecular weight of all kinds of gas is different, they will occur gravity segregation under the action of gravity field.

井筒内的天然气都是由多种气体组成的混和天然气，由于气体各组分的分子量不同，会在重力场作用下发生重力分异，从而使井筒内混和气体的性质与单一气体有很大差异。

In the model the exit area ratio, solid particle mass ratio, fuel enthalpy of combustion, jet gas molecular weight, chamber stagnation temperature, flight Math number etc. have been considered.

在该模型中考虑了底排出口面积比，排气固相颗粒质量比，燃料热值，燃气分子量，燃烧室总温，飞行马赫数等因素。
