Heat Transfer and Phase Change

3D Simulation of Air-Glass Heat Exchange in a Set of Vials

G. Mongatti[1], A. Borelli[1]
[1]Marchesini Group, Pianoro, Italy

In this model a three-dimensional heat transfer analysis was performed by using COMSOL Multiphysics\' Heat Transfer Module. The model is about the heating of a set of vials (Figure 1) in a current of hot air in the laminar regime. We used time dependent studies to predict the thermal ... En savoir plus

BHE Field Design by Superposition of Effects in Space and Time

S. Lazzari[1], E. Zanchini[1]
[1]DIENCA - University of Bologna, Bologna, Italy

A design method for BHE fields in the absence of groundwater flow is presented, based on the superposition of effects. The effects of any periodic heat load with a period of one year can be obtained by a weighted sum of the effects of a monthly unit step heat load, properly displaced in ... En savoir plus

Exergy Analysis of a Water Heat Storage Tank

F. Dammel[1], J. Winterling[1], K. J. Langeheinecke[2], P. Stephan[3]
[1]Institute of Technical Thermodynamics, Technische Universität Darmstadt, Germany
[2]IAV, Gifhorn, Germany
[3]Institute of Technical Thermodynamics/Center of Smart Interfaces, Technische Universität, Darmstadt, Germany

A combined heat and power (CHP) plant generates both electricity and useful heat. A heat storage tank enables a decoupling of electricity and heat delivery. In this study a cylindrical hot water storage tank is considered. Charging, holding time and discharging are numerically simulated ... En savoir plus

Numerical Simulation of Warm-Air Drying of Mexican Softwood (Pinus Pseudostrobus)

S. Sandoval Torres[1], E. Hernández-Bautista[1], J. Rodríguez-Ramírez[1], A. Carrillo Parra[2]
[1]Instituto Politécnico Nacional, CIIDIR, Oaxaca, Mexico
[2]Facultad de Ciencias Forestales, Universidad Autónoma de Nuevo León, Linares, N.L. México

In this work, the numerical simulation of Mexican softwood (Pinus pesudostrobus) drying is presented by solving a physics-based model. The model was developed by considering the heat and mass transport and the representative elementary volume, which involves the solid, liquid and gas ... En savoir plus

Building Energy Simulation Using the Finite Element Method

J. van Schijndel[1]
[1]Eindhoven University of Technology, Eindhoven, The Netherlands

In order to predict, improve and meet a certain set of performance requirements related to the indoor climate of buildings and the associated energy demand, building energy simulation (BES) tools are indispensable. Due to the rapid development of FEM software and the Multiphysics ... En savoir plus

Air Convection on a Micro Hotplate Gas Sensor

S. Gidon[1], M. Brun[1], S. Nicoletti[1], P. Barritault[1]
[1]Commissariat Energie Atomique, LETI, Minatec Campus, Grenoble, France

Monitoring of indoor CO2 concentration is of particular interest to detect room occupancy in order to optimize power consumptions of building. One approach to monitor the indoor CO2 concentration is to use optical detection using specific absorption lines of CO2 molecules in the infrared ... En savoir plus

Thermal Simulations of a LED Light Using COMSOL Multiphysics

M. Maaspuro[1]
[1]University of Turku, Turku, FInland

An experimental LED light composed of a multi-chip LED-module, a LED driver and an efficient heat sink, was investigated using COMSOL Multiphysics software and the Heat Transfer Module. In an LED light heat is mainly generated in the LEDs but some amount of heat is generated also in the ... En savoir plus

Thermal and Fluid Dynamics Studies Applied to Steel Industry

G. Tracanelli[1], M. Culos[1]
[1]Studio di Ingegneria Industriale Tracanelli, San Vito al Tagliamento, Italy

The energy pay back is one of the most interesting field especially in the steel industry where this contribution is strictly connected to steams and emissions inside and outside the plant. Perhaps, this application is sometimes disturbed by a strong variation of emissions (\"off gas\"). ... En savoir plus
