The application of pulsed electric fields (PEF) is well known in the food industry as an advanced technology for mass transfer improvement. A new potential adaptation area of PEF could be extracting a valuable antioxidant called polyphenol from wet olive pomace (WOP) which is a by-product of olive oil production. The modelling includes the PEF effects on the WOP which is flowing through a ...

There is a great need for an effective drug treatment of the posterior eye, as the major reason for visual disability in industrial countries is Age-related Macular Degeneration (AMD). In USA alone, there are almost 2 million people affected by AMD . A virtual pharmacokinetic 3D model of the human eye is built to address this problem, using COMSOL Multiphysics® software, based on the Finite ...
Micromechanical Design of Novel Thermal Composites for Temperature Dependent Thermal Conductivity - new

The freezing curve of the food material was extracted from Differential Scanning Calorimetry experiments. A heat conductive model was generated in COMSOL, including the thermo-physical characteristics and the phase transition behavior. The resulting temperature-time evolutions at different positions in space were in excellent agreement with our experimental data. Changing scale, the variation ...

Solar radiation is a prominent contributor of energy in buildings, and can be transmitted directly into a building through opaque surfaces, but it can also be absorbed by building components (i.e. walls, roofs etc.). This study discusses the use and effect of ventilated facades, with an external facade cladding, a sub-structure anchored to the wall surface of the building under solar radiation, ...

The design of a RFID-enabled temperature sensor is described in this paper. In this sensor, a change in temperature causes structural beams to bend, which results in a proportional displacement of the plates of the capacitor. Plates\' displacement results, in turn, in changing the value of its capacitance. The capacitor of the sensor is coupled to the LC resonant network of a passive RFID tag. ...

Kheer is a popular Indian dairy dessert prepared from concentrating milk with simultaneous cooking of rice grains. Conventional methods of preparing kheer have limited its mechanized production. Therefore, a conceptual design of continuous kheer-making machine has been prepared which among other components consists of a heating section for cooking kheer. The present study investigates the CFD ...
Analysis of Heat Transfer in a Complex Three Dimensional Structure Fabricated by Additive Manufacturing - new

Biomedical Engineering Department, University of Connecticut, Storrs, CT, USA
The goal of this study was to create a three dimensionally designed biomedical device with multiple functionalities and analyze its simulated heat transfer. The device would be fabricated through additive manufacturing; specifically electron beam melting (EBM). EBM has a feature size constraint of 1 mm (acceptable for this design) and is only capable of manufacturing titanium alloys ; a ...

In this paper describes an original method for indirect measurement of the vapor pressure and temperature in the keyhole in electron beam welding. This method is based on the determination of the concentration of chemical elements in the vapor above the welding zone. Taking into account these data model is built 2D diffusion processes with heat and mass transfer elements in the melt, which ...
