Fluid Flow Pattern Visualisation: An Alternative Approach Using Highly Resolved Heat Transfer Experiments

Peter Ott, Alexandros Terzis, Bernhard Weigand

The present study demonstrates an alternative approach for describing fluid flow characteristics very close to the wall, using locally resolved heat transfer experiments. Convection coefficients on the base surface and around a surface mounted vortex gener ...

Turbulence and zonal flow structures in the core and L-mode pedestal of tokamak plasmas

Olivier Sauter, Laurent Villard, Stephan Brunner, Trach-Minh Tran, Ben McMillan, Gabriele Merlo, Julien Stanislas Pierre Dominski

Zonal flows (ZF) play a crucial role in regulating ion temperature gradient (ITG) turbulence. In previous global gyrokinetic simulations [I] using the ORB5 code with the adiabatic electron model, it was observed that long-lived ZF structures, leading to a ...

Fine-resolution two-phase flow heat transfer coefficient measurements of refrigerants in multi-microchannel evaporators

John Richard Thome, Navid Borhani, Sylwia Szczukiewicz

The time-averaged two-phase flow heat transfer coefficients were determined with a very fine resolution based on infra-red (IR) temperature measurements conducted over a 1 cm(2) heated area of a multi-micro-, channel evaporator. This experimental investiga ...

Energy Integration in the cement industry

François Maréchal, Alberto Mian, Matthias Bendig, Gaia Piazzesi

Cement production is an energy intensive industrial process that requires heat to be supplied at high temperature levels under the constraints of gas-solid heat exchange phenomena and the kinetics of chemical reactions. In this paper, the use of Pinch Anal ...

Heat Management for Process Intensification of Fast Exothermic Reactions in Microstructured Reactors

Julien Haber

Nowadays, the production in fine chemical and pharmaceutical industry is mostly carried out in large scale batch reactors having typically dimensions of a few meters to satisfy the demand of the market. Even though this technology has been widely used and ...

Cooling High Heat Flux Micro-Electronic Systems using Refrigerants in High Aspect Ratio Multi-Microchannel Evaporators

Etienne Costa-Patry

Improving the energy efficiency of cooling systems can contribute to reduce the emission of greenhouse gases. Currently, most microelectronic applications are air-cooled. Switching to two-phase cooling systems would decrease power consumption and allow for ...

A new building energy model coupled with an urban canopy parameterization for urban climate simulations-part I. formulation, verification, and sensitivity analysis of the model

Alain Clappier, Andrea Krpo

The generation of heat in buildings, and the way this heat is exchanged with the exterior, plays an important role in urban climate. To analyze the impact on urban climate of a change in the urban structure, it is necessary to build and use a model capable ...

Heat Transfer Measurements in a Turbine Cascade: Taking Advantage of the Thermal Bahaviour of a PSP Sensor

Peter Ott, Magnus Jonsson

Film cooling experiments are commonly performed with Pressure Sensitive Paint (PSP). The oxygen sensitive probe molecules allow for measurement of the adiabatic film cooling effectiveness by detecting the concentration of a tracer-gas with different oxygen ...

Numerical Modeling of Annular Laminar Film Condensation in Circular and Non-Circular Micro-Channels under Normal and Micro-Gravity

Stefano Nebuloni

A theoretical and numerical model to predict film condensation heat transfer in mini, micro and ultra micro-channels of different internal shapes is presented in this thesis. The model is based on a finite volume formulation of the Navier-Stokes and energy ...
