Mobile and static sensors in a citizen-based observatory of water

Michael Lehning, Wolf Hendrik Huwald, Steven Vincent Weijs, Tristan Jonas Brauchli

Understanding and forecasting water resources and components of the water cycle require spatially and temporally resolved observations of numerous water-related variables. Such observations are often obtained from wireless networks of automated weather sta ...

Double-diffusive interfaces in Lake Kivu reproduced by direct numerical simulations

Alfred Johny Wüest

Double diffusion transforms uniform background gradients of temperature and salinity into "staircases" of homogeneous mixed layers that are separated by high-gradient interfaces. Direct numerical simulations (DNS) and microstructure measurements are two in ...

Wind-tunnel experiments of turbulent flow over a surface-mounted 2-D block in a thermally-stratified boundary layer

Fernando Porté Agel, Wei Zhang, Corey Dean Markfort

Turbulent flows over complex surface topography have been of great interest in the atmospheric science and wind engineering communities. The geometry of the topography, surface roughness and temperature characteristics as well as the atmospheric thermal st ...

Interface structure and flux laws in a natural double-diffusive layering

Alfred Johny Wüest, Martin Schmid

The diffusive regime of double-diffusive convection generates staircases consisting of thin high-gradient interfaces sandwiched between convectively mixed layers. Simultaneous microstructure measurements of both temperature and conductivity from the stairc ...

Experimental study on flow boiling heat transfer of multiport tubes with R245fa and R1234ze(E)

John Richard Thome, Bruno Agostini, Farzad Vakili Farahani

The upward flow boiling experiments were carried out in a flat aluminum extruded multiport tube, which is composed of 7 parallel rectangular channels (1.1 mm × 2.1 mm) with hydraulic diameter of 1.4 mm. Two refrigerants, R245fa and R1234ze, the latter a re ...

Pressure drop data and prediction method for enhanced external boiling tube bundles with R-134a and R-236fa

John Richard Thome, Eugene van Rooyen

The pressure drops of external flow over enhanced tube bundles were experimentally obtained at both adiabatic and diabatic conditions using R-134a and R-236fa as test fluids. The tests were carried out at saturation temperatures of 5 and 15 degrees C, mass ...

Experimental study of the impact of large-scale wind farms on land-atmosphere exchanges

Fernando Porté Agel, Wei Zhang, Corey Dean Markfort

Large-scale wind farms, covering a significant portion of the land and ocean surface, may affect the transport of momentum, heat, mass and moisture between the atmosphere and the land locally and globally. To understand the wind-farm-atmosphere interaction ...

Evanescent straight tapered-fiber coupling of ultra-high Q optomechanical micro-resonators in a low-vibration helium-4 exchange-gas cryostat

Tobias Kippenberg, Albert Schliesser

We developed an apparatus to couple a 50-mu m diameter whispering-gallery silica microtoroidal resonator in a helium-4 cryostat using a straight optical tapered-fiber at 1550 nm wavelength. On a top-loading probe specifically adapted for increased mechanic ...
