Solders are typically used to join similar or dissimilar metals, referred to as substrates. In some cases solders are also used to join completely different classes of materials. For example, a joint between copper busbar and silicon solar cell represents a set of dissimilar substrates. In the formation of a solder-substrate couple, the system must have been subjected to at least a single ...

Estimation of Tungsten Melt-Zone Size During Transient Heat Loads - new

[1]Institute for Plasma Research, Gandhinagar, Ahmedabad, India

Electron beam has a wide range of applications in the material processing and joining techniques. Apart from that, it has also been utilized to simulate steady as well as transient fusion reactor relevant heat loads. Transient heat load events spontaneously occur in the fusion reactor. Several hundred megawatt of power is dumped upon the plasma facing material surfaces for a very short ...

The main purpose of SPIDER (Source for the Production of Ions of Deuterium Extracted from RF plasma) test facility is the investigation and optimization of a negative ion beam produced by the full size ion source for ITER NBIs (Neutral Beam Injectors). Thermal, transient, non-linear FE (Finite Element) analyses and also electrostatic analysis have been performed as a feasibility study, to ...

High Temperature Process Simulation

O. Geoffroy, and H. Rouch
INOPRO, Villard de Lans, France

The crystal growth industry uses high temperature processes. To improve production efficiency, a good knowledge of thermal effects is necessary. We show in this article a methodology to get reliable data by mixing simplified models, sensitivity studies and parameters adjustments. The precision is improved by comparison with experimental measurements.

Loading Conditions in the Feed Sparger of a Steam Drum Influenced by Thermal Shock

Bhabha Atomic Research Centre, Mumbai, Maharashtra, India

Steam drum in a nuclear power plant is one of the important components of Primary Heat Transport (PHT) system where steam is separated from the steam water mixture. Steam water mixture emanating from the reactor core is separated in a steam drum. Separated steam goes to the turbine whereas separated water after mixing with incoming feed water returns to the reactor. The entire feed water flow is ...

Modeling Thermal Bridging at Interface Conditions: Analysis of Solutions for Reducing Thermal Bridges Effects on Building Energy Consumption

C. Balocco[1], E. Marmonti[1]
[1]Dipartimento di Energetica, Università di Firenze, Firenze, Italy

In Europe considerable building activity can be expected over the coming decades; Net Zero Energy Buildings refers to a building with minimal power, until maximum 15 kW/m^2. In both cases this requires very well insulated buildings with minimal thermal bridges. Concrete balconies, that extend the floor slab through the building envelope, are a common example of thermal bridging, where structural ...

[1]NASA, Marshall Space Flight Center, Huntsville, AL, USA

Some NASA efforts are focused on improving current systems that utilize fixed beds of sorbent pellets by evaluating structured sorbents, seeking more robust pelletized sorbents, and examining alternate bed configurations to improve system efficiency and reliability. For the bulk separation of CO2 and H2O, temperature changes due to the heat of adsorption are significant, requiring modeling and ...

The Hygro-Thermal Improvement of a Mounting System to Fasten Roof Workmen to Flat Roofs - new

H. L. Schellen[1]
[1]Eindhoven University of Technology, Eindhoven, The Netherlands

A Dutch firm manufactures a mounting system to fasten roof workmen to the roof of a flat roof building to prevent them from falling down from the roof. The system is mounted to the flat roof afterwards, i.e. after the completion of the thermal insulated roof. Because of the mechanical strength and stiffness properties of the system, it is manufactured using (stainless) steel. The steel, ...
