Analysis of Solar Hot Water Storage

K.O. Lund
Applied Chemical and Engineering Systems

In a Solar Hot Water System, the hot water from the solar collector enters at the top of the storage tank. A relevant question concerning the storage is what will the outlet temperature be. In the present work we present a way to model Solar Hot Water Systems.

Schwerpunkte dieses Vortrages bilden die Verknüpfungen folgender Themenkomplexe: • Werkstoffwissenschaft • Energieverfahrenstechnik • Qualitätsmanagement • Polyoptimierung Für derart umfassende Aufgabenstellungen gibt es zur Zeit keine Softwarelösungen. So ist z.B. die Kundenforderung nach Garantie erhöhter Schlagarbeit bei stark abgesenkten negativen Temperaturen in keinem ...

Numerical simulation of separation flows with FEMLAB 3.1

Carlo Gualtieri
University of Napoli Federico II
Naples, Italy

Flow separation is a common and interesting phenomenon in fluid mechanics with significant effects in practical applications. Thus, it has been the focus of intensive study for many years. The objective of this presentation is to investigate laminar separation flows over a backward-facing step and over a rectangular trench using COMSOL. --------------------------------- Carlo Gualtieri ...

The Unroutinary Loads on the LBT Adaptive Secondary Mirror

C. Del Vecchio
INAF-OAA, Firenze, Italy

The thin shell of the LBT Adaptive Secondary Mirror has been manufactured, optically polished, and delivered. The operations and tests required before finally mounting it on the telescope have to be run very carefully, as they imply loads completely different from the ones of the adaptive operational modes - studied in the past with very encouraging results. Deformations and stresses that occur ...

Microband Electrodes in Microchannels: Edge Diffusion and Wall Effects

Microfluidics enables the miniaturization and integration of sensors into advanced analytical devices. Electrochemical detection is currently one of the preferential techniques of use in microfluidic devices due to its sensitivity, low cost and compatibility with new microfabrication techniques. In this work, we first model the electrochemical response of a set of microband electrodes placed ...

A non-Conventional use of COMSOL to Solve a Complex 3D Geometrical Problem

J. P. Caire, and F. Jomard
LEPMI, ENSEEG, Saint Martin d'Hères, France

The purpose of this study was the optimization of an industrial furnace from a thermal point of view. Such a cylindrical furnace contains an Al-Mg molten alloy covered by a KCl-NaCl molten salt layer floating on it to prevent alloy evaporation. When tilting the cylindrical furnace, it was necessary to compute the relation between the salt and alloy volumes and the area of the liquid alloy/salt ...

Pre-design of a Molten Salt Thorium Reactor Loop

J. P. Caire, and A. Roure
LEPMI-ENSEE, Saint Martin d'Hères, France

The generation 4 of molten salt reactors using the thorium cycle are characterized by a temperature close to 1000 oC. The very large heat transfers involved between the reactor core and the external parts with minimal thermal losses are a major issue. This study investigated a possible inner loop made of a series of conventional graphite filter plate exchangers, pipes and pumps, using the COMSOL ...

Analysis of a Spatial Filtering Design for Capacitive Flow Measurements

D. Hrach, A. Fuchs, and H. Zangl
Institute of Electrical Measurement and Measurement Signal Processing, Graz University of Technology, Graz, Austria

In this paper, a simulation of a capacitive flowmeter utilizing a spatial filtering technique is presented. The flowmeter consists basically of ring shaped electrodes placed sequentially in the flow direction on the outside of a pipe. The paper introduces an electrode layout and describes the modeling of the electrodes to achieve the required simulation accuracy.We show the functionality of the ...
