Creating a low-carbon, non-nuclear economy: The case of Taiwan

Original story at MIT News Can Taiwan create a low-carbon economy without nuclear energy? One MIT researcher finds out. After the 2011 Fukushima nuclear disaster, energy experts and policymakers around the world began to reassess the future of nuclear power. Countries, including Japan and Germany, have since scaled back or plan to shut down their nuclear power — sparking a global debate ...

CFD modelling of electrohydrodynamic gas flow in an electrostatic precipitator

Modelling of the flow velocity fields for electrohydrodynamic flow in a wire-to-plate type electrostatic precipitator was achieved. From calculations for the flow employing different flow models, the Chen-Kim k − ε turbulent model appeared to be the most appropriate choice to obtain a quantitative image of the resulting mean flow field and downstream wake flow of the rear wire, although this was ...

Automatic contrast enhancement using Selective Grey-Level Grouping

In this paper, we introduce a method called Automatic Selective Grey-Level Grouping (ASGLG), which enables automatic contrast enhancement of an image based on the principle of transforming the skewed histogram of the original image into a uniform histogram after the recent work on Selective Grey-Level Grouping (SGLG) of the image by Chen et al. (2006a). In SGLG the user needs to specify the ...

Decision making and technology selection in water (reuse) applications

In recent years, a large number of developed countries have considered water reuse schemes as a mandated alternative water resource to tackle water scarcity. With increasing knowledge on and understanding of the merits of water reuse in developing communities, a number of planned water reuse schemes have also been established (Chen et al., 2012; Fatta-Kassinos et al., 2011a). The range of water ...

Numerical modelling of gas dispersion from road tunnels in urban environments: comparison with field experiment data

Numerical computations and field experiments of the dispersion of a tracer gas from a road tunnel in Paris are compared. The Reynolds-averaged Navier-Stokes equations, combined with the k-ε turbulence model of Chen and Kim, are solved using the finite-volume code PHOENICS. Results are shown to be sensitive to the turbulence modelling and to the parameterisation of turbulence and drag forces ...

Evaluation of the biosolids compost maturity in south Isfahan wastewater treatment plant

As a promising alternative for biosolids disposal, land application of composted biosolids has increased in the past decade (Goldstein and Steuteville, 1996). One of the important factors affecting the successful use of biosolids compost for agricultural purposes is stability and maturity it. Application of unstable or immature compost may cause slow plant growth and damage crops by competing for ...

Hydraulic and Thermal Response of Groundwater–Surface Water Exchange to Flooding in Experimental Aquifer

Summary The effects of flooding on interactions between streams and shallow aquifers are poorly studied due to the unpredictable nature of flooding events. This study examines groundwater-surface water interactions in a constructed experimental meander over several simulated flood events using hydrologic and thermal monitoring. Detailed steady-state hydraulic head measurements were taken of the ...

Effect of organic loading on the performance of aerated submerged fixed-film reactor (asffr) for crude oil-containing wastewater treatment

A large amount of water is used in oil industry for a wide variety of purposes and basic portion of it leaves this industry as wastewater containing oil, phenols, different solvents, and toxic substances (Zhao, et al., 2006; Toril, 2001). Such wastewater can pollute water bodies, soil, and even the air if it is not treated (Yang, 2000; Chen, 2002; Vegueria, 2002). Biological treatment processes ...
