Dust-proof Characteristics of a Bypass Flow Type Flowmeter Using a Hot Wire

概要

論文の詳細を見る
The authors experimentally examined dust deposits on a hot wire when employed as an air flowmeter. The following points were considered: surface temperature, hot wire diameter, air flow velocity, inertial separation effect, and collision ratio of dust particles onto the hot wire in a dust-proof type flowmeter. The last two points were evaluated using simulations based on experiments and theoretical calculations. As a result, it was found that the output change due to dust deposits on the hot wire could be prevented using a bypass flow type flowmeter, in which the inertial separation effect was taken into consideration.
