Optimal Supply Angle of Upside Air Supply in Manned Spacecraft Cabin-Based Air Age
MetadataShow full item record
The age of air in the workaround of a manned spacecraft cabin that contain astronauts, apparatus and simple living establishments was numerically simulated by use of commercial software and a standard k-e turbulence model. An air inlet installed in the two top corners with a removed stagger mode supplied the air. Simulation results showed that the less the supply angle, the fresher the air, and the greater the air exchange efficiency. A 0° supply angle is advised if no block is in the ceiling.
