Large Eddy Simulation of Vertical Axis Wind Turbine Wakes

In this study, large eddy simulation (LES) is combined with a turbine model to investigate the wake behind a vertical-axis wind turbine (VAWT) in a three-dimensional turbulent flow. Two methods are used to model the subgrid-scale (SGS) stresses: (a) the Sm ...

Improved Nonaqueous Synthesis of TiO2 for Dye-Sensitized Solar Cells

Michael Graetzel, Morgan Mertens Stefik, Markus Niederberger

Nonaqueous synthesis routes have emerged as a powerful platform for directly obtaining diverse metal oxide nanoparticles with high crystallinity and tunable compositions. The benzyl alcohol (BA) route, for example, has been applied toward dozens of oxides ...

The Effect of Free-Atmosphere Stratification on Boundary-Layer Flow and Power Output from Very Large Wind Farms

Fernando Porté Agel, Mahdi Abkar

Large-eddy simulation is used to study the influence of free-atmosphere stratification on the structure of atmospheric boundary-layer flow inside and above very large wind farms, as well as the power extracted by the wind turbines. In the simulations, tuni ...

In-Spray Supercharging of Peptides and Proteins in Electrospray Ionization Mass Spectrometry

Hubert Girault, Yury Tsybin, Luca Fornelli, Yu Lu, Sasa Miladinovic, Krzysztof Marek Piech

Enhanced charging, or supercharging, of analytes in electrospray ionization mass spectrometry (ESI MS) facilitates high resolution MS by reducing an ion mass-to-charge (m/z) ratio, increasing tandem mass spectrometry (MS/MS) efficiency. ESI MS superchargin ...

Interaction between large wind farms and the atmospheric boundary layer

Fernando Porté Agel, Yu-Ting Wu, Hao Lu

Accurate prediction of atmospheric boundary layer (ABL) flow and its interactions with wind turbines is of great importance for optimizing the design and efficiency of wind farms. This study first focuses on recent efforts to develop and validate a large-e ...

Large-Eddy Simulation of Wind-Turbine Wakes: Evaluation of Turbine Parametrisations

Fernando Porté Agel, Yu-Ting Wu

Large-eddy simulation (LES), coupled with a wind-turbine model, is used to investigate the characteristics of a wind-turbine wake in a neutral turbulent boundary-layer flow. The tuning-free Lagrangian scale-dependent dynamic subgrid-scale (SGS) model is us ...

Mixing efficiency and energy consumption for five generic microchannel designs

Albert Renken, Lioubov Kiwi, Madhvanand Namadeo Kashid

Mixing is an essential part of chemical processes. In the present work, homogeneous mixing at relatively high throughput for a single microchannel (of 1-18 mL/min) was investigated in microchannels with different dimensions, cross sections and mixing eleme ...

Experimental investigation of prechamber autoignition in a natural gas engine for cogeneration

Daniel Favrat, Stefan Heyne, Michael Meier

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 ...
