•空气和水蒸气被视为理想气体•空气连续混合良好•无过饱和•一维空气和颗粒流•稀释系统（无颗粒相互作用）•颗粒呈球形•离散粒度分布（箱）•颗粒内均匀温度•可发生过冷却•混合相颗粒不是空间分解•在颗粒温度下颗粒表面发生相变•绝热隧道壁•颗粒和空气的流动是连续流•基本CV是绝热的，质量是守恒的
• Air and water vapor are treated as ideal gases• Air is continually well mixed• No supersaturation• 1-D air and particle flow• Dilute system (no particle interaction)• Particles are spherical• Discrete particle size distribution (bins)• Uniform temperature within the particle• Supercoolingcan occur • Mixed phase particles are not spatially resolved• Phase change occurs at particle surface at particle temperature• Adiabatic tunnel walls• The flow of particles and air is a continuous stream• The fundamental CV is adiabatic and mass is conserved
