A numerical study on Nox emission from an industrial furnace utilizing high temperature air combustion (HTAC) technology was done. The basic concept of the regenerative burner including heating a diluting of fresh air by flue gas was implemented in a two-dimensional furnace model. Governing equations in conjunction with a turbulence model and an overall chemistry model were solved using an impl...

Abstract Background Nitrate contamination of groundwater often occurs in urban and industrial areas due to point non-point sources anthropological activities. Groundwater constitutes a significant portion the water supply system for Bahir Dar City Ethiopia, though level pollution is not known. This study was conducted assess extent aquifer (nitrate) based on contaminant vulnerability risk mappi...

The goal of this study is to determine the vulnerability groundwater in northern Iraq's Nineveh Plain by utilizing DRASTIC method and geographic information systems (GIS). In context human or environmental systems, refers potential for harm as a result stress disturbance, it may be related particular system, hazard, group hazards. map includes three categories: very low, medium. Following resul...

Vulnerability assessment to delineate areas that are more susceptible to contamination from anthropogenic sources has become an important element for sensible resource management and land use planning. This contribution aims at estimating aquifer vulnerability by applying the DRASTIC model as well as utilizing sensitivity analyses to evaluate the relative importance of the model parameters for ...
