Abstract
The measured thrust in the test facility is affected by secondary airflow and the thrust is different from gross thrust. Thrust correlation parameter between outdoor and test facilities is called cell factor. In this paper, CFD application for cell factor prediction has been investigated. Both overall test cell model and outdoor cell model are analyzed by CFD. The results are compared with measurement's aerodynamic parameters, which are cell bypass ratio and front cell depression, in the test cell and are agreed well. In addition, it is checked that CFD also predict cell factor precisely.
