9 10 Ozone is a major pollutant of indoor air. Many studies have demonstrated the adverse health effect of 11 ozone and the byproducts generated as a result of ozone-initiated reactive chemistry in an indoor 12 environment. This study developed a Computational Fluid Dynamics (CFD) model to predict the ozone 13 distribution in an aircraft cabin. The model was used to simulate the distribution of...

This research work aims to investigate and subsequently optimize the operating parameters that affect thermal comfort indoor air quality in school environment. The proposed design uses a coupling between solar ventilation absorption chiller-air conditioning. heating tower of an adsorption chiller connected conditioning system can be driven by waste heat from (exhausted hot air) thank this linka...

Streamflow, suspended sediment transport and meteorological variables at two elevations were measured through the 1990-1992 field seasons at Lake C2, northern Ellesmere Island, as part of the Taconite Inlet Lakes Project. The objectives were to determine the extent to which suspended sediment flux responded to climatic variability, and to ascertain which meteorological variable was most strongl...

The weight of the oxidizer dominates the take-off weight of rocket based propulsion systems. Therefore, airbreathing engines that consume the oxygen from the atmosphere offer a promising alternative. At flight conditions with Mach numbers above 6 SCramjet propulsion systems represent a better suited concept than ramjet systems, as the high static temperature resulting from the deceleration to s...

During the past two decades, the utilization of Active Chilled Beam (ACB) systems as promising air-conditioning systems has becoming increasingly prevalent in Europe, North America and Asia. However, the studies on air distribution of ACB systems are still inadequate. The air distribution has a great impact on thermal comfort. The ununiformity of air distribution will easily lead to turbulent f...

1 of 2 DESCRIPTION Air embolism following the administration of intravenous paracetamol is a risk because it is stored in a rigid container, and therefore requires an air inlet to allow infusion. 1 At the end of the infusion, if the giving-set is not clamped, air may be entrained, particularly into a central vein. Venous air embolism of a volume of 5 ml/kg may cause cardiac arrest, but consider...

The surfaces of poplar wood fibers were modified using high-temperature hot air (HTHA) treatment and silane coupling agent. The single factor test was then used to investigate the performances (e.g., the change of functional groups, polarity, cellulose crystallinity, and thermal stability) of modified poplar wood fibers (mPWF) through Fourier transform infrared spectrometry, X-ray diffraction a...

drying is one of the most important steps in raisin processing. during this step, initial moisture content decreases up to 15-17% (db) for suitable storage. achieving optimum drying conditions can affect the processing time and improve raisin quality. temperature, air velocity and pretreatment are important factors in the quality of the grape drying process. in this research, the effect of temp...

supersonic separators have found extensive applications in dehumidification of natural gases since 2003. unlike previous studies, which have investigated the inlet conditions and nozzle geometry of supersonic separators for pure fluids, the present study employed a combination of momentum, heat, and mass transfer equations along with virial equation of state (eos) to inspect the effect of inlet...

Shell and Tube heat exchangers are the heat exchangers that are most widely used in industries and for other commercial purposes. There are many techniques that have been utilized to enhance the heat transfer performance of the shell and tube heat exchangers. Air bubble injection is one of the promising and inexpensive techniques that can create turbulence in the fluids resulting in to enhancem...
