High Pressure Processing (HPP) is a leading non-thermal food processing technology that is often cited as a major technological innovation in food preservation. Although it is very early to place this emerging technology among the list of breakthroughs in food processing, HPP has started to become a viable commercial alternative for pasteurisation of value added fruits, vegetables, meat, and ...

Laser Welded Blank solutions enable to reduce vehicles weight and to optimize their crash performances by means of simultaneous tuning of different grades and thicknesses. The present work aims to characterize numerically and experimentally materials mixing during laser welding. For better understanding of materials mixing based on convection-diffusion process in case of full penetrated laser ...

The ampacity of a cable depends on the cross section of its conductor. When selecting a cable design for a specific application it is of interest to choose the lowest possible conductor cross section in order to reduce material costs. Therefore an exact calculation of the ampacity is necessary (it is usually limited by the thermal resistance of the insulating cable materials). Commonly the ...

Laser drilling of titanium and its alloys is widely used in aerospace industry, as it offers selective removal of material at high accuracy and speed. However, laser drilling often inherits defects such as large heat affected zone, micro cracks and recast layer. These defects depend upon complex melting and solidification phenomena happening due to interaction of high-intensity laser with the ...

Plasma torches are used in processing of materials and in energy industry for producing plasma. In a non-transferred arc plasma torch, an electric arc can be glowed by applying a direct current (DC) between the cathode and anode, both placed inside the torch. Then, the plasma (Fig. 1) is obtained by heating, ionizing and expanding a working gas, introduced into the chamber of the torch upstream ...

Induction heating is multiphysics process, which includes electromagnetic induction and heat transfer. Both the physics are nonlinearly coupled with each other. In this paper, mathematical modeling of induction heating of MS tube for elevated temperature NDT application is presented. Mathematical modeling of electromagnetic field is done by using magnetic vector potential formulation. Heat ...

This document discusses the simulation of a downsized nozzle for fused deposition modelling (FDM), namely the E3D HotEnd Extruder with manufactured diameters of 200-400 μm in the nozzle tip. The nozzle has been simulated in terms of heat transfer and fluid flowgiving an insight into the physical behavior of the polymer inside the nozzle. The extruder contains a nozzle, a heater block, a ...

Thermoelectric power generation has been envisioned as a clean energy alternative to conventional thermal to electric power generation for decades due to its noiseless and low-cost operation. However, a typical thermoelectric generator suffers from low device efficiency, so it has been a constant endeavor for thermoelectric researchers’ community to consider alternate thermoelectric materials ...

1. Introduction The topology optimization method is becoming increasingly popular as a design tool for multiphysics systems [1,2]. Topology optimization of fluid-thermal systems has been presented for example in  for forced convective heat transfer and in  for natural convection problems. In this work, topology optimization including density filtering and projection is applied to ...
