An increased share of renewable energies is regarded as an integral part of a strategy towards a sustainable future. With regard to the heat supply sector this may be achieved using solar thermal collectors or heat pump systems with borehole heat exchangers. During the last years solar thermal and geothermal systems have generally been installed separately. Now, several proposals are discussed ...

Steam methane reforming is a widely studied process because of its importance for hydrogen production. A two-dimensional membrane-reactor model was developed to investigate the steam-methane reforming reactions. The use of membrane as membrane-reactor separator offer us few advantages because it help in continuously removing the hydrogen from the reaction zone, shifting the chemical equilibrium ...

Lake Victoria is the largest tropical lake in the world and is very important for environment and economy in East Africa. The hydrodynamic processes in the shallow (40-80 m deep) water system are unique due to its location at the equator which makes Coriolis effects noticeable also for vertical transport. The limited river inflow, and the large surface area compared to its volume make Lake ...

The ubiquitous nature of biofilms has led to a growing need to be able to detect, control, and maintain or remove them. Therefore a robust testing platform that allows for multiple analytical techniques is required to better understand their multitude of properties. The development of the self-contained microfluidic-based electrochemical cell portion of a multifaceted analysis system is ...

Electrochemical flow cells have found widespread use in analytical chemistry due to their short response time, high sensitivity and selectivity. The geometrical flexibility and therefore, the ease of coupling the electrochemical to other experimental techniques has attracted considerable interest for applications in electrocatalytic research as well. Such coupling is far more cumbersome with the ...

Sodium is used as a coolant in Fast Breeder Reactors. Eddy Current Flowmeter (ECFM) is used for measurement of sodium flow in the primary pump and at the outlet of the subassemblies. Eddy Current Flowmeter (ECFM) works on the principle of change in the magnetic field profile due to induced eddy currents as a result of sodium flow. It consists of a central primary winding, energized from an A.C. ...

The study of multiphase flows inside the microfluidic devices has received much attention recently because of its applications in heat and mass transfer, mixing, microreaction, emulsification and most importantly in MEMS and lab-on-a-chip. We study the influence of an electric field on the interfacial morphologies and their transitions, the phenomenon termed electrohydrodynamics. The literature ...

The Atmosphere Revitalization Recovery and Environmental Monitoring (ARREM) project was initiated in September of 2011 as part of the Advanced Exploration Systems (AES) program. Under the ARREM project, testing of sub-scale and full-scale systems has been combined with multiphysics computer simulations for evaluation and optimization of subsystem approaches. In particular, this paper describes ...
