Description
hree-dimensional thermal air flow analysis computer program for an airplane cabin air distribution system has been developed in order to facilitate design improvements. This program is based on an incompressible Navier-Stokes code in generalised three-dimensional coordinates (IN3D). The original program was modified to add capabilities of computing thermal (buoyancy) effects and contaminants (carbon dioxide) dispersion and treating the influence of internal obstructions such as passenger seats. Verification tests have also been conducted with a full-size cabin mockup that has the same configuration and conditions as those used in the computer program. Presents a description of modifications of the program, the technique used in modelling an airplane cabin, a description of the configuration and conditions analysed and a description of verification tests, and a discussion of the prediction accuracy, usefulness, and problems encountered as a result of comparing analysis and test data.
