Electrochemistry in Supercritical Fluids: A Mini Review

Manuel Alejandro Méndez Agudelo, Kathryn Ellen Toghill, Patrick Voyame

A brief overview of the literature relating to electrochemical studies and processes undertaken in supercritical fluids is presented. This review mostly concerns carbon dioxide and hydrofluorocarbons, given the accessibility of their supercritical states, ...

An Onset of Nucleate Boiling Criterion for Horizontal Flow Boiling

John Richard Thome, Daniel Favrat, Olivier Zürcher

An extensive database has been collected for the evaporation of two hydrofluorocarbon refrigerants (HFC- 134a and the zeotropic mixture HFC- 407C) and the natural refrigerant ammonia (R-717). A model to predict the onset of nucleate boiling has been succes ...

Contribution to the heat transfer analysis of natural and substitute refrigerants evaporated in a horizontal tube

Olivier Zürcher

The substitution of CFC refrigerants in refrigeration systems, heat pumps and organic Rankine cycles, requests a good knowledge of the heat transfer and pressure drop properties of substitute fluids. A contribution to this international effort is proposed ...

Evaporation du réfrigérant HFC 407C sur des tubes lisses ou à surface améliorée.

John Richard Thome, Daniel Favrat, Olivier Zürcher

The substitution of CFC refrigerants in refrigeration systems, heat pumps and organic Rankine cycles for heat recovery, requires good methods for predicting heat transfer of substitute fluids. The measurements in the LENI test facility (concentric tubes wi ...

Evaporation de nouveaux réfrigérants sur des tubes à surface améliorée.

John Richard Thome, Daniel Favrat, Olivier Zürcher

The substitution of old refrigerants in refrigeration systems, heat pumps and organic Rankine cycles for heat recovery, request a good knowledge of heat transfer properties of substitute fluids. The test measurmements in LENI test facility (concentric tube ...

Two-Phase Heat Transfer to New Refrigerants.

John Richard Thome

The conversion to the new alternative refrigerants caused by the greenhouse and ozone effects is now replacing nuclear reactor analysis and safety as the major driving force in two-phase heat transfer research. Extensive studies are underway on pool boilin ...
