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 ... En savoir plus
With the evolving trend of electrification in transportation, electric machines with higher power density and higher efficiency are demanded which results in the thermal limit of the stator winding becoming more of a key constraint. The achievable current density in stator windings is ... En savoir plus
Mathematical description of microwave drying requires the solution of two different physics: electromagnetics in the microwave oven cavity and food material and, transport process (mass, momentum and heat transport) in the food material. Maxwell’s equations for electromagnetics were ... En savoir plus
The authors are currently investigating the use of bulk high temperature superconductors as trapped field magnets (TFMs) in order to increase the electrical and magnetic loading of an axial gap, trapped flux-type superconducting electric machine. In electric machines, the use of ... En savoir plus
Microwave drying of fruits and vegetables in a domestic oven has been found to result in large textural changes in the product such as puffing, crack formation and even burning due to the inhomogeneous heating of the microwaves. Microwave drying of potatoes is a complex interplay of ... En savoir plus
Photoacoustic (PA) imaging has matured into a clinical modality for tissue imaging and functional cancer cell research. It uses a pulsed laser to irradiate a region and generate a thermally-induced acoustic pressure wave that can be collected by an ultrasound transducer. The optical ... En savoir plus
Measuring soil moisture content plays an important role not only for sustaining dry farming but also for soil mapping. Our work includes developing a soil moisture sensor which is based on the principle of the Dual-Probe Heat-Pulse method to measure soil moisture content. To validate ... En savoir plus
Working performance of an disconnector is affected by maximum permissible temperature which is caused by the ohmic heat losses of & eddy current losses. Since experimental testing is expensive & time consuming, a 3D thermal analysis model of double break rotating blade (DBRB) 33 ... En savoir plus
3D-scanning of rooms and entire buildings is state of the art and commonly used to obtain and save the digital building structure. This information simplifies appropriate planning for modifications, to equip rooms, for interior design, etc. With a new approach of IR-heating and IR ... En savoir plus
ZF-Friedricshafen AG is one of the biggest supplier of Automatic Gear Shifters for the modern cars and ZF-Automatic Gear Shifter needs sensing of five or seven positions (e.g. P, R, N, D, S) and (M+, M-) etc. Hall Sensors and Inductive Sensors are two automatic choices for such ... En savoir plus
