Comfort is an important requirement of civil aircraft, and whether the cabin airflow organization is reasonable or not will directly affect the comfort and health of passengers. The most popular and reliable prediction,design and analysis methods of cabin airflow organization for civil aircraft are the experimental measurement and numerical simulation. This paper describes the two methods, both have advantages and disadvantages. The limited simulated cabin experiments cooperate with many CFD simulations are proved to be the most effective, reliable, economical, and rapid research means.
