In this paper, a numerical study is conducted on the melting and solidification process of metal foam/paraffin wax with cyclic heating and cooling. A mathematical model based on the Brinkman-Frochheimer extended Darcy equation and the local thermal non-equilibrium model (LTNE) is ... Per saperne di più
Four-point probe resistance measurements on the microscale can induce significant localized heating which can be a source of measurement error, or an opportunity to measure thermal properties of materials. The amplitude and phase delay of the temperature affect micro four-point probe ... Per saperne di più
With the ReactorSTM the relationship between surface structure and catalyst activity under industrially relevant conditions can be investigated. It enables atomic-scale observations of model catalysts under conditions approaching those used by the chemical industry. It consists of a ... Per saperne di più
At Leoni, we are not only working towards even more reliable, performant cables by simulating their electric, magnetic, mechanical as well as thermal properties but also bring our customer applications to our design board. Based, amongst others on multi-physical simulations, we prepare ... Per saperne di più
Laser technologies such as welding, cutting and metal deposition are widely used in the industry. High quality requirements regarding process products cause that there is often a need to monitor the process. For this purpose, optical sensors integrated with a laser head are often used. ...

Abstract: In order to study thermal conditions and air flows in an office room, 3D FEM simulation model was created. The room is enclosed by walls, floor and ceiling which thermal characteristics are specified by typical heat transfer coefficients and specific heat capacities. Space ... Per saperne di più
We present the model of THz sensor based on thermoelectric Bi-Sb thin films. The model is based on an electromagnetic heating interface and combines radiofrequency and heat transfer modules. The studied frequency was 0.14 THz, irradiation power 30 mW. Films had a thickness of 150 nm and ... Per saperne di più
A quantification of spatial and temporal evolution of laser-induced plume would enhance the comprehension of high speed imaging results and allow optimizing the acquisition conditions for the emission spectroscopy. What temperature and concentrations of the evaporating species are ... Per saperne di più
Calorimetry is the method of choice for determining one of the most elementary physical quantities: heat, Q [in J]. Depending on the individual issue a wide range of techniques, devices and methods are available for users [1]. One approach is called isothermal microcalorimetry (IMC). It ... Per saperne di più
In this numerical investigation, the effective thermal conductivities (ETC) of periodic complex structures are evaluated. These structures are to be used as packing in Heat-Integrated Distillation Columns (HIDiC). Only high-porosity (>85%) complex structures are considered for ... Per saperne di più
