Flow boiling data and prediction method for enhanced boiling tubes and tube bundles with R-134a and R-236fa including a comparison with falling film evaporation

John Richard Thome, Eugene van Rooyen

New enhanced boiling tubes from Wolverine Tube Inc. (Turbo-B5) and Wieland-Werke AG (Gewa-B5) were investigated using R-134a and R-236fa as test fluids. The tests were done at saturation temperatures of 5 and 15 degrees C, mass flow rates from 4 to 35 kg m ...

Double diffusion in saline Powell Lake, British Columbia

Alfred Johny Wüest

Powell Lake contains a deep layer of relic seawater separated from the ocean since the last ice age. Permanently stratified and geothermally heated from below, this deep layer is an isolated geophysical domain suitable for studying double-diffusive convect ...

Surface heat flux variability of a large lake: Lake Geneva, Switzerland

David Andrew Barry, Ulrich Lemmin, Damien Bouffard, Abolfazl Irani Rahaghi

The heat budget of a lake is a fundamental component of physical limnology, and is strongly dependent on the surface heat flux. However, the surface energy exchange depends on several factors, making it difficult to estimate. In this study we employed seve ...

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

Fernando Porté Agel, Wei Zhang, Corey Dean Markfort

Turbulent boundary-layer flows over complex topography have been extensively studied in the atmospheric sciences and wind engineering communities. The upwind turbulence level, the atmospheric thermal stability and the shape of the topography as well as sur ...

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 ...

Characterising Internal Heat Transfer in Thermal Protection Systems

Sophia Haussener, Pénélope Leyland, Nikhil Banerji

Thermal protection systems (TPS) are employed for spacecraft to survive high temperature conditions during atmospheric re-entry. For space shuttle type re-entries, the use of ceramic tiles shield the payload from exposure to these high heat fluxes. Recent ...

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 ...

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 ...

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 ...
