The purpose of this study was to compare environmental conditions and mice in cages with four different mechanical ventilation designs and a static isolator cage. Environmental conditions (air velocity, temperature, relative humidity, bedding weight change, airborne dust, NH3, and CO2) were compared for each cage type (n = 5 per cage). Bedding type was chipped hardwood. Mouse response in each c...

A new diagnostic has been developed that is capable of obtaining simultaneous two-phase velocity measurements in a gasoline direct-injection fuel spray. This technique utilizes a two-laser (double-pulse) twocamera (double-frame) setup to simultaneously image the injected fuel and entrained air to determine the 2D velocity vector fields of both phases using cross-correlation particle image veloc...

The possibility of building a high voltage electrostatic air pump for cooling of microelectronics is investigated. Existing cooling technology no longer provides adequate heat dissipation due to excessive heat generation caused by the growing component density on electronic devices. Heat sink fins are packed more closely to increase the heat exchange surface area, resulting in narrower channels...

The Adriatic Sea meteotsunami research and warning network is described. The network is located in the middle Adriatic, an area where the most destructive of the Adriatic meteotsunamis (destructive tsunami-like sea level oscillations generated by air pressure oscillations) occur. The network consists of three microbarograph meteorological stations, and is supplemented by four permanent tidegaug...

A model of the trumpet has been studied in which the NavierStokes equations are used to calculate the air pressure and velocity, while the lips are described using the swinging lip model of Adachi and Sato. This approach allows us to determine the pressure throughout the lip region, and thus calculate the lip motion without the approximations necessary in previous modeling work.

Gaspers installed in commercial airliner cabins are used to improve passengers' thermal comfort. To understand the impact of gasper airflow on the air quality in a cabin, this investigation measured the distributions of air velocity, air temperature, and gaseous contaminant concentration in five rows of the economy-class section of an MD-82 commercial aircraft. The gaseous contaminant was simul...
