The main driver for small scale turbomachinery in domestic heat pumps is the potential for reaching higher efficiencies than volumetric compressors currently used and the potential for making the compressor oil-free, bearing a considerable advantage in the ...
Microscale two-phase flow is at present one of the hottest topics of heat transfer research, both in academia and in the industry. The miniaturization of two-phase flow systems, which has led to numerous experimental and theoretical challenges not yet comp ...
Structural stability issues in planar solid oxide fuel cells arise from the mismatch between the coefficients of thermal expansion of the components. The stress state at operating temperature is the superposition of several contributions, which differ depe ...
Multistage hydraulic systems and methods for converting the potential energy of a pressurized gas, particularly air, into mechanical work operating in motor, and for producing compressed gas from the mechanical work of the rotating shaft (A1.1 ) when rotat ...
As our awareness of the dangers of global climate change grows, the development of new renewable energy technologies is of primary importance in the effort to reduce emissions of carbon dioxide and other greenhouse gases. Rapid increases in the price of oi ...
In the present paper, a model of a solar tower power plant (STPP) is presented. This is the result of a Master semester project led at the Laboratory for Industrial Energetic Systems (LENI) at the Swiss Federal Institute in Lausanne (EPFL). The modelized p ...
In order to sort out the physics that is important in many plasma experiments, data in three dimensions 3D are becoming necessary. Access to the usual cylindrical vacuum vessel is typically restricted to radially or axially insertable probes that can pivot ...
The main goal of this master is to define and analyse the best layout options for a combined cycle power plant. The gas turbines used for this combined cycle are known. Methods for power augmentation of the gas turbine are considered. Different layouts and ...
A novel ignition concept based on autoignition in an unscavanged prechamber is currently being developed at the Laboratory for Industrial Energy Systems (LENI). On a single cylinder test engine a series of experimental runs (CR=8.5-14, =1-1.6, RPM=1150/150 ...
