Energetic Macroscopic Representation of A Linear Reciprocating Compressor Model
Alfred Rufer, François Gallaire, Philippe Barrade, Mahbod Heidari
This article introduces the energetic macroscopic representation (EMR) as approach for the dynamic nonlinear modeling of a reciprocating air compressor. EMR has been introduced recently for research development in complex electromechanical systems and is b ...
Elsevier2015Experimental investigation of kink initiation and kink band formation in unidirectional glass fiber-reinforced polymer specimens
Thomas Keller, Anastasios Vassilopoulos, Wei Sun
The failure mechanism of non-slender glass fiber-reinforced epoxy prismatic specimens subjected to axial compression and different temperatures was investigated. Digital image correlation was used to map and derive the failure modes. The failure mode chang ...
Elsevier2015Experimental investigation of a Thermally Driven Heat Pump based on a double Organic Rankine Cycle and an oil-free Compressor-Turbine Unit
Daniel Favrat, Jürg Alexander Schiffmann, Jonathan Demierre, Johannes Wegele
This paper presents the experimental investigation of a concept of Thermally Driven Heat Pump (TDHP), based on the coupling of a vapor compression heat pump cycle and an Organic Rankine Cycle (ORC). The studied concept uses a single stage centrifugal compr ...
Elsevier2014Innovative isothermal oil-free co-rotating scroll compressor-expander for energy storage with first expander tests
The development of an efficient isothermal turbine and compressor is essential for the realization of a small-scale compressed air energy storage (CAES). This article presents the theoretical development of an oil-free co-rotating scroll air compressor and ...
Pergamon-Elsevier Science Ltd20143D ALE Finite-Element Method for Two-Phase Flows With Phase Change
John Richard Thome, Navid Borhani, Gustavo Rabello Dos Anjos
We seek to study numerically two-phase flow phenomena with phase change through the finite-element method (FEM) and the arbitrary Lagrangian-Eulerian (ALE) framework. This method is based on the so-called one-fluid formulation; thus, only one set of equati ...
Taylor & Francis2014Development of a New Generation of Ammonia Sensors on Printed Polymeric Hotplates
Nico de Rooij, Danick Briand, Francisco Molina Lopez, Andres Felipe Vasquez Quintero, El Hadji Malick Camara
Conducting polyaniline-based chemiresistors on printed polymeric micro-hotplates were developed, showing sensitive and selective detection of ammonia vapor in air. The devices consist of a fully inkjet-printed silver heater and interdigitated electrodes on ...
American Chemical Society2014Dynamic flow control and performance comparison of different concepts of two-phase on-chip cooling cycles
John Richard Thome, Jackson Braz Marcinichen, Duan Wu, Bruno Michel
A hybrid on-chip two-phase cooling cycle specifically designed to cool server boards with chips of high performance computers was experimentally evaluated considering steady-state and transient operation of two parallel pseudo-chips and auxiliary electroni ...
Elsevier2014Advances in Electronics Cooling
John Richard Thome, Jackson Braz Marcinichen, Jonathan Olivier, Nicolas Lamaison
This article highlights the advantages of on-chip microchannel cooling technology, based on first-and second-law analysis and experimental tests on two types of cooling cycles, the first driven by an oil-free liquid pump and the second by an oil-free vapor ...
Taylor & Francis2013Dynamic Modeling and Simulation of Two-stage Compression Heat Pumps with Flash Economizer
Daniel Favrat, Jean-Baptiste Carré, Samuel Henchoz, Simon Gailledrat
Multistage heat pumps are one of the most efficient technologies for delivering heat at temperatures below 100°C, Thanks to their fairly high exergy efficiency. In the recent years the development of radial compressors mounted on gas bearings have unlock t ...
2013Two-phase flow operational maps for multi-microchannel evaporators
John Richard Thome, Navid Borhani, Sylwia Szczukiewicz
The current paper presents new operational maps for several different multi-microchannel evaporators, with and without any inlet restrictions (micro-orifices), for the two-phase flow of refrigerants R245fa, R236fa, and R1234ze(E). The test fluids flowed in ...
