Multiphysics Simulations of Granular Sludge on the Optimization of Effluent Treatment Plant
Multiphysics Simulations of Physico-chemical and Biological Treatment of wastewater is increasing due to the demand for cost efficient plant design and utilization. Among the many processes, a thorough understanding of the settling behavior of an activated granular sludge in the ... Read More
Diffusion Modeling in TGA in Context of CO2 Gasification of Char
The Thermo- Gravimetric Apparatus (TGA) is often used for kinetics determination. In TGA setup, gasification reaction may be limited by the reach (diffusion) of the gasification agent to the internal surfaces of the char particles. In addition to this, after some time, ash is formed ... Read More
Transport of Vocs through Bioflim in Biotrickling Filters
Realising the interlinkage of nature and engineering are of paramount essential while comprehending the basics of system’s performances. Application of biotechniques in air pollution control is one such emerging scientific area, where the understandings of these complex systems demand ... Read More
Design and Simulation of Sensors to Detect Methanol
The Direct Methanol Fuel Cell (DMFC) working is dependent on the concentration of methanol in water before it is introduced in the anode. DMFC has a high energy density when generating electrical power from fuel, and is an attractive power source for portable devices. A fundamental ... Read More
Modeling and Optimization of a Mg-Metal Hydride Rectangular Tank in the Hydriding Process
Hydrogen storage can be considered as a key factor in the development of hydrogen economy. Hydrogen storage in a magnesium hydride MgH2 is a very promising technique for numerous of reasons. Magnesium is abundant, relatively cheap, life – friendly , weight storage capacity of 7.6% ... Read More
A Study of Thermo-Fluid Behavior in Tubular Metal Hydride Beds in the Hydriding Process
Hydrogen, the most abundant element in the universe, has great potential as an energy source, and can be generated from renewable energy sources. We used COMSOL for the solution of the energy, mass and momentum balance equations that describe the hydrogen absorption and desorption ... Read More
Reactive Transport Processes in Compacted Bentonite
The Swedish Organization for Radioactive Waste (SKB) is considering disposal High Level Wastes in a deep underground repository. Bentonite clay is planned to be used in the near-field of the waste packages as buffer material. The buffer is expected to provide a favorable environment with ... Read More
