Velocity profiles and interface instability in a two-phase fluid: investigations using ultrasonic velocity profiler

Anton Schleiss, Giovanni De Cesare, Azin Amini

In the present study the velocity profiles and the instability at the interface of a two phase water-oil fluid were investigated. The main aim of the research project was to investigate the instability mechanisms that can cause the failure of an oil spill ...

Springer-Verlag2009

A comprehensive review of flow boiling characteristics and flow pattern visualization of refrigerant/lubricant oil mixtures is presented in this paper. First, various parameters influenced by the lubricant oil in convective boiling of refrigerants, such as ...

Open innovation in SMEs: Trends, motives and management challenges

Vareska van de Vrande

Open innovation has so far been studied mainly in high-tech, Multinational enterprises. This exploratory paper investigates if open innovation practices are also applied by small- and medium-sized enterprises (SMEs). Drawing oil I database collected from 6 ...

Disentangling oil weathering at a marine seep using GC×GC: Broad metabolic specificity accompanies subsurface petroleum biodegradation

Jeremy Samuel Arey

Natural seeps contribute nearly half of the oil entering the coastal ocean. However, environmental fate studies generally monitor fewer than 5% of these petroleum compounds. Hence, the rates and relevance of physical, chemical, and biological weathering pr ...

Disentangling oil weathering using GCxGC. 2. Mass transfer calculations

Jeremy Samuel Arey

Hydrocarbon mass transfers to the atmosphere and water column drive the early weathering of oil spills and also control the chemical exposures of many coastal wildlife species. However, in the field, mass transfer rates of individual hydrocarbons to air an ...

Contractile floating barriers for confinement and recuperation of oil slicks

Azin Amini

Marine oil spills can cause serious environmental damages to natural resources and to those whose sustenance depends upon these resources. Unfortunately experience shows that even the best efforts have not prevented occasional occurrences of major accident ...

EPFL2007

Biodiesel, a mixture of fatty acid methyl esters (FAMEs) derived from animal fats or vegetable oils, is rapidly moving towards the mainstream as an alternative source of energy. However, the behavior of biodiesel, or blends of biodiesel with fossil diesel, ...

Disentangling oil weathering using GCxGC. 1. Chromatogram analysis

Jeremy Samuel Arey

Historically, the thousands of compounds found in oils constituted an “unresolved complex mixture” that frustrated efforts to analyze oil weathering. Moreover, different weathering processes inflict rich and diverse signatures of compositional change in oi ...

Intube Flow Boiling of R-407C and R-407C/Oil Mixtures. Part 1: Microfin Tube

John Richard Thome, Daniel Favrat, Olivier Zürcher

Intube evaporation tests for R-407C and R-407C/oil are reported for a microfin tube. The tests were run at a nominal inlet pressure of 6.45 bar (93.5psia) at mass velocities of 100, 200 and 300 kg/m2s (73581, 147162 and 220743 lb/h ft2) over nearly the ent ...
