The Air Tra c Flow Management (ATFM) service is designed to ensure an optimum ow of air tra c to or through areas within which tra c demand at times exceeds the available capacity of the Air Tra c Control (ATC) system. It protects air tra c control from overload situations which are potentially dangerous to the safety of air tra c. It also ensures the maximum utilization of ATC capacity in all ...

Many organisms increase the air or water flow adjacent to olfactory surfaces when exposed to appropriate chemical stimuli; such 'sniffing' samples fluid from a specific region and can increase the rate of interception of odorant molecules. We used hot-wire anemometry, high-speed videography and flow visualization to study air flow near the feathery olfactory antennae of male silkworm moths (Bom...

Below-grade stormwater storage tunnels are designed to provide relief for collection networks during intense rain events. Air must be evacuated as the tunnel fills and, depending on the system geometry, the air may become pressurized. This research presents an investigation on various ways that the air pressurization influences the water flow. The investigation used an experimental apparatus co...

thermal modeling of an automotive cabin was performed in this paper to predict the inside cabin air temperature. to implement this task, thermal and ventilation loads were estimated and the mass and energy balance conservation equations for dry air and water vapor with considering a new parameter (air circulation ratio) as well as the balance equations of internal components of a cabin were der...

Healthy adult albino rats of either sex of Wistar strain weighing 150 to 250 g were used after approval of the Institutional Ethics Committee. They were kept on standard pellet diet and were allowed free access to food and water. The doses of antitubercular drugs (isoniazid (I)-27 mg/kg/day, rifampicin (R)-54 mg/kg/day, pyrazinamide (Z)-135 mg/kg/day) were extrapolated from daily human dose usi...

The gas flow estimation is crucial for the proper operation and monitoring of turbocharged (TC) engines with a torque structured engine control unit (ECU). This paper presents mean value models developed for modeling gas flow over the compressor, the turbine and the wastegate (WG) in a TC gasoline engine not equipped with a hot film air-mass flow meter (HFM). The turbine flow ...

Much energy is lost through excess air flow in and out of process heating equipment. Energy saving opportunities from managing air flow include minimizing combustion air, preheating combustion air, minimizing ventilation air, and reconfiguring openings to reduce leakage. This paper identifies these opportunities and presents methods to quantify potential energy savings from implementing these e...
