Investigation of the Benzene Concentration and Distribution in Tehran Using Geographic Information System Modelling
Introduction and purpose: Air pollution has been recognized as the most important environmental risk factor worldwide. Benzene which is one of the four pollutants attributed to BTEX (Benzene, Toluene, Ethylbenzene, and Xylene) has been proven to be a carcinogenic component. These pollutants can be easily absorbed and taken into the body via inhalation. With this background in mind, the present ...
متن کاملNumerical Investigation of the Influence of Sand Particle Concentration on Long Radius Elbow Erosion for Liquid-Solid Flow
Erosion caused by sand transportation in flow changing devices is a serious concern in the hydrocarbon and mineral processing industry, which entail to failure and malfunction of flow devices. In this study, computational fluid dynamics (CFD) with discrete phase models (DPM) were employed for analysis of carbon steel long radius 90-Degree elbow erosion due to the sand concentration of 2, 5 and ...
متن کاملNumerical Investigation on the Effect of Tunnel Height on Drag Reduction in a High Speed Trimaran
There are different methods to reduce drag in high speed hulls. One of these methods is a change in the shape of the body by adding longitudinal side tunnels. In this paper it has been attempted to determine the influence of the tunnel height on hydrodynamic characteristics of the hull to achieving an optimum shape for the tunnel. To achieve this purpose, numerical simulation of the problem has...

1 Ventilation System in Tunnel during Construction Works
Preface Construction works always involve danger and their environment is not always clean. In case of tunnelling works, especially in tunnels to be constructed with the drill and blast method, the problems on the safety and health such as the ones by dust and poison gas are serious subjects. This paper discusses the principle of ventilation system in tunnel during construction to provide good ...
