Potential of Passive Cooling Techniques for Modern Houses in the Tropical Climate of Malaysia - Analysis of the Indoor Thermal Environment for Various Ventilation Strategies | 2010 | English
This paper discusses the potential of passive cooling techniques for Malaysian modern houses with the aim of reducing air-conditioning usage.
An Energy Efficient Air Conditioning System using Displacement Ventilation and Chilled Ceiling for Modern Office Buildings | 2010 | English
Thermal comfort and indoor air quality (IAQ) play a vital role in creating a pleasant and healthier indoor environment for occupants.
The performance of stratum ventilation, a recently developed ventilation strategy, is assessed in terms of thermal comfort and indoor air quality using experimental and computational fluid dynamics (CFD) techniques.
The results of this investigation revealed the airflow distribution from a new design of supply diffuser under non-isothermal conditions.
The Aluminerie Alouette Inc. (AAI) smelter in northern Quebec, Canada recently completed a major plant expansion that includes a new casthouse for the continuous production of low-profile, air-cooled aluminium sows.
If inhaled, welding fumes can be harmful to health, thus exposure must be controlled.
Much attention is given to the consequences of airborne particles on human health and well-being.
A planned new train tunnel under the central parts of Stockholm was intended to be ventilated by natural ventilation and the movement of the trains.
In a simple single-zone building with two openings under an opposing wind, a macroscopic theoretical analysis of smoke flow direction and smoke mass flow rate is carried out.
Principles and Calibration of Solid Phase Microextraction Fibre (Passive Sampler) for Measurements of Airflow and Air Infiltration in Dwellings | 2010 | English
Tracer gas techniques have been the most appropriate experimental method of determining airflows and ventilation rates in houses.
Application of CFD in Modelling Wind-Induced Natural Ventilation of Buildings - A Review | 2010 | English
This paper reviews the application of CFD for designing and parametric studies of wind-induced natural ventilation. The approaches employed in such applications of CFD are whole-domain and domain-decoupled CFD modelling.
Effects of Wall Shape Changes in Indoor Air Circulation - Studies on Concave and Convex Walls | 2010 | English
In naturally ventilated environments, indoor temperatures are directly related to the air circulation and conditions of the built environment.
Accessing the Thermal Mass above Suspended Ceilings via a Perimeter Gap: a CFD Study of Naturally Ventilated Spaces | 2010 | English
There is a growing desire to reduce peak temperatures within non-domestic buildings by accessing the thermal mass of separating floors. These floors are typically formed of concrete and can store reasonable amounts of heat.
In contrast to mechanical ventilation, natural ventilation's performance is usually impacted by uncertain factors, including wind fluctuations, outside air temperature variations, and occupants' behaviours.
Application of the principle of the balance of mechanical energy gives a constraint on the possible values of the junction coefficients at a duct system junction.
Experimental and CFD Airflow Studies of a Cleanroom with Special Respect to Air Supply Inlets | 2010 | English
Investigations were carried out into the airflow in a non-unidirectional airflow cleanroom and its affect on the local airborne particle cleanliness. The main influence was the method of air supply.
Stack-Driven Ventilation in Two Interconnected Rooms Sharing a Single Opening and Connected to the Exterior by a Lower Vent | 2010 | English
This paper describes the transient ventilation of two interconnected rooms.
It has been found that, among the tools and methods available for the energy calculation of double envelope elements, there are some debatable aspects such as: the selection of correlations for calculating the convective heat transfer coefficient
The governing equations in duct system flow analyses are nonlinear, and iterative solution methods must be used. A suitable initial flow rate guess may be needed to start the calculations so that a converged solution can be finally achieved.
