Abstract
This paper focuses on the passageway design of the main sieve diaphragm that is the key point to reduce the pressure drop of a gas mask canister. Three types of the passageways are designed to explore the aerodynamic behaviors of the flow inside a canister. The models include the hole, rib-strip and honeycomb types. The 3-D numerical simulations of flows have been applied to determine the pressure drops in the models. The simulation results reveal the smallest pressure drops on the passageway of honeycomb type, because the structure of honeycomb type is stronger enough to avoid the deformation of the main sieve diaphragm. So the passageway of honey comb type can provide larger channel area and more uniform channel distribution to reduce the pressure drop. The analysis of the flow structure, such as the velocity profile and the distribution of dead zone in the models, is also studied.
