Interacting Turbulent Plumes in a Naturally Ventilated Enclosure
The interaction of turbulent plumes is examined in the context of building ventilation flows. Recent models for natural ventilation have been based on simplified treatment of the heat sources in a ventilated enclosure. These models treat buoyancy sources as plumes and assume that they do not interact. To improve the applicability of these models to buildings we examine the effects of plume-plum...
متن کاملAn Investigation on Ventilation Air distribution within Rectangular and Circular Enclosures
One of the important parameters that dictate the effectiveness of ventilation system is air change rate. The air change rate provides overall effectiveness of ventilation in an enclosed space and it needs to be examined with age of air particles to decide about overall effectiveness. Age of air particles is the time air at a location spends inside the enclosure and hence provides useful informa...
متن کاملNumerical studies on natural ventilation flow in an enclosure with both buoyancy and wind effects
Computational Fluid Dynamics (CFD) is used to predict natural ventilation flows in an enclosure with upper and lower openings connected to the environment. The natural driving forces are wind combined with buoyancy. CFD simulations were carried out by varying the strengths of buoyancy under a constant assisting wind effect. Simulation results of the volume flow rates through the enclosure, the ...

This study has been done in a raajor brake-shoe factor.'. Air samples were taken and dustlevels determined according to OSHA code, revealing a dust load in weighting and shootingsaloons ranging from 2 to 16.88 mg/nr Measurement and counting of asbestos fibers weredone using OSHA ID 160/ code and permissible exposure levels. Asbestos fiber counts in sampled areas were higher than the time weigh...
متن کاملThe fluid mechanics of natural ventilation-displacement ventilation by buoyancy-driven flows assisted by wind
This paper describes the fluid mechanics of natural ventilation by the combined effects of buoyancy and wind. Attention is restricted to transient draining flows in a space containing buoyant fluid, when the wind and buoyancy forces reinforce one another. The flows have been studied theoretically and the results compared with small-scale laboratory experiments. Connections between the enclosure...
