Experimental evaluation of the thermal performances of a thermosyphon cooling system rejecting heat by natural and forced convection

John Richard Thome, Filippo Cataldo

In the present paper, a closed-loop thermosyphon cooling system for power electronics has been developed and tested. The evaporator is a multi-microchannel heat sink designed for high heat fluxes. The power electronics module is emulated by four independen ...

Pergamon-Elsevier Science Ltd2017

Open-pore aluminium foams are of interest in thermal management of power electronics due to their large specific surface area, low weight and relatively high thermal conductivity. The replication process is a low-cost and simple foam manufacturing method t ...

Numerical Quantification of Coupling Effects for Radiation-Conduction Heat Transfer in Participating Macroporous Media: Investigation of a Model Geometry

Sophia Haussener, David Yann Samuel Perraudin

Radiative-conductive heat transfer in porous media is usually investigated by decoupling the heat transfer modes and solving the volume-averaged continuum equations using effective transport properties. However, both modes are naturally coupled and couplin ...

Role of data processing in measuring temperature gradients with DOE Schardin's schlieren #2

Pramod Rastogi, Sai Siva Gorthi

Flows having a variable fluid density can be visualized with optical methods. Recently, a background distortion technique, which can be considered a type of Schardin's schlieren #2, was proposed to study the refractive index variation in fluid and hence to ...

Thermal Analysis of the advanced single-stage planar actuator

The Advanced Single-stage Planar Actuator (ASPA) is a nanometer-accurate magnetically levitated planar actuator with moving magnets. It is designed at the Eindhoven University of Technology in collaboration with an industrial partner active in the semicond ...

Atmospheric Boundary Layer Dynamics of Transitional Flows over Complex Terrain

Daniel Nadeau

Recent advances in boundary-layer meteorology are beginning to allow the study of atmospheric flow phenomena that have previously been poorly understood. In this dissertation, we study the effects of complex terrain and unsteady regimes on the atmospheric ...

A simple model to study the decay of turbulent kinetic energy (TKE) in the convective surface layer is presented. In this model, the TKE is dependent upon two terms, the turbulent dissipation rate and the surface buoyancy fluctuations. The time evolution o ...
