Simulation Research on Ventilation Control of Gaseous Pollutants in Urban Sentry Boxes
نویسندگان
چکیده
The tiny spaces of sentry boxes in cities, such as mobile security guards, highway toll booths, etc., are mostly located beside roads with harsh outdoor environments. Due to office demands, work windows often need be kept or frequently opened. intrusion pollutants through the leads deterioration indoor air quality, and threatens health employees. This paper takes gaseous pollutant NO 2 representative discusses effective ventilation design scheme for improving quality box openings using two attached modes carrier. Taking vertical wall-attached an example, formation curtain at window hole its barrier performance were studied. conclusion is that when supply velocity sufficient form a complete hole, it can effectively block pollutants. horizontal shows clean delivered space openings, also well improved due dilution effect, but effect positive pressure control not obvious large opening. conclusions provide guidance openings.

Modeling and Simulation Research on Dynamics of Missiles with Deflectable Nose Control
The dynamic characteristics of deflectable nose missiles with rotary single-channel control were investigated in this paper. Firstly, the effective angle of attack, effective angle of sideslip and quasi-body coordinates were introduced based on the spin characteristics of the missile’s body. Secondly, considering the interaction between the missile’s nose and body, the rigid kinetic model of mi...
