EAS107 - Modeling and Simulation of Multi-Phase Fluids using Easy5

Horizontal spacer

This course will provide the student with an understanding of how to model closed-loop, multi-phase systems using EASY5. Applications include HVAC, environmental controls, and refrigeration. The governing physical principles and the corresponding equations of state will be presented as well as a detailed example model.
