Aircraft cabin airflow analysis based on CFD

Abstract

Abstract: Based on engineering application, the correlative models of aircraft cabin are set up, cabin air distribution system is designed. Then, analysis of cabin airflow and air age has been carried out with CFD. Results show that: a.change of air supply temperature has influence on corresponding area and few on other zones; b. the area of airflow outlet, amount of recycling air and position of outflow valve have less effect on distribution of cabin air temperature and speed; c. first-class cabin gets more fresh air, business cabin gets less fresh air and economic cabin gets least.

Key words: airliner, aircraft cabin, airflow, air age
