Auxiliary Power Units can play an important role in reducing vehicle emissions, especially in diesel and kerosene driven vehicles. In conventional vehicles the electricity supply comes from a generator that is directly coupled to the propulsion engine. New generation of fuel cell APUs exclusively use Solid Oxide Fuel Cells with some developments in high temperature polymer electrolyte membranes ...

For combustion simulations, the wall temperature and heat transfer is an important piece of information. Coal combustion systems typically have walls that are initially a cast ceramic, but, with time, slag is deposited on the surface and coal and soot are incorporated into the slag. It is this slag coated ceramic that determines the rate at which heat is transferred from the wall combustion ...

A key issue for the development of a LENR power unit involves the measurement and energy output of the reaction. Our team is currently studying a gas loaded nanoparticle-type cluster power unit  which pressurizes various nanoparticle alloys with either deuterium or hydrogen. The principal elements in the various nanoparticle alloys are Nickel, Palladium and Zirconium, with each alloy ...

The ubiquitous commercial use of Lithium-Ion batteries (LIBs) has increased interest in their implementation into efficient energy storage systems for clean and renewable power sources and the electrical transportation industry. Unfortunately, LIBs are not yet technological mature to meet various commercial demands. Consider the following challenges for example,: (1) lower than desired effective ...

Low-dimensional semiconductor nanostructures, in which charge carriers are confined in a number of spatial dimensions, are the focus of much solid-state physics research, offering superior optical and electronic properties over their bulk counterparts. Both two-dimensional (2D) and zero-dimensional (0D) structures have seen wide-ranging applications in laser diodes, solar cells and LEDs to name ...

The French National Waste Management Agency (Andra) envisages the safe disposal of High-Level Waste Intermediate-Level Long-Lived Waste through deep geological storage (multibarrier). Waste storage is based on the Callovo-Oxfordian formation (CallOx). It has been updated a reactive transport model accounting for the chemical and thermal evolution of a HLW cell. Improvements are a better ...

The Life+ GreenWoolF project is aimed at demonstrating that green hydrolysis with superheated water is an effective way to convert wool wastes into organic nitrogen fertilizers. The core of the process is represented by the reaction tank (Figure 1) in which the hydrolyses reaction takes place. The temperature of the material during the reaction is one of the most influencing parameter and has to ...

This work describes a model for plasma formation in the keyhole and above the EBW zone. The parameters of the plasma are closely connected to the characteristics of the thermal action of the electron beam on the welded metal, which allows operational control and study of EBW. The ionization intensity of the vapour due to beam electrons and high-energy secondary and backscattered electrons is ...

Introdução: A medição adequada de vazão de fluidos é de grande importância nos processos industriais, pois tem implicações diretas na qualidade, produtividade, segurança e eficiência dos processos. Assim, torna-se necessário compreendermos como os fluidos se comportam para baixas velocidades, podendo, dessa forma, projetar estruturas que possam trabalhar em uma faixa de operação mais larga ou ...

Mixing is an important process in a microfluidic system such as micro total analysis systems. In this paper, design and analysis of various micro-mixers for enhancing the mixing performance is presented. At first, the basic principles of mixing along with the mixing length and mixing time calculations are discussed. In general, macro-scale mixing is achieved with turbulence while mixing in micro ...
