Two-Phase Flow Boiling in a Single Layer of Future High-Performance 3D Stacked Computer Chips

John Richard Thome, Navid Borhani, Sylwia Szczukiewicz

The present study focuses on an experimental investigation of two-phase flow boiling in a silicon multi-microchannel evaporator, which emulates a single layer of a 3D stacked computer chip. The micro-evaporator is comprised of 67 parallel channels, each ha ...

Prototype of a thermally driven heat pump based on integrated Organic Rankine Cycles (ORC)

Daniel Favrat, Samuel Henchoz, Jonathan Demierre

The concept studied in this work is a low power ORC-ORC heat pump system (providing about 20 kW heat at the condenser) and that is composed of an ORC power cycle driving a reversed ORC heat pump cycle, both cycles using the same fluid. The centrifugal comp ...
