Development of a Coupled Air and Particle Thermal Model for Engine Icing Test Facilities

• 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...
