The quantitative measure of dissipative properties of different numerical schemes is crucial to computational methods in the field of aerospace applications. Therefore, the objective of the present study is to examine the resolving power of Monotonic Upwi... see more

Staged pressurized oxy-fuel combustion is an advanced technology to be employed for the combustion and carbon capturing processes. This technology is promising because of relatively low costs, low emissions and high-efficient power generation with exhaust... see more

Le présent travail est une contribution à l’étude numérique des jets libres turbulents axisymétriques de fluides non réactifs et réactifs, comme on peut les rencontrer dans les brûleurs de types Bunsen. Le but recherché est la compréhension et la maîtrise... see more

Gas turbines are important energy-converting equipment in many industries. The flow inside gas turbines is very complicated and the knowledge about the flow loss mechanism is critical to the advanced design. The current design system heavily relies on emp... see more

A large-eddy simulation (LES) study of vertical-axis wind turbine wakes under uniform inflow conditions is performed. Emphasis is placed on exploring the effects of subgrid-scale (SGS) modeling on turbine loading as well as on the formation and developmen... see more

In the search of a new weapon for combat in short range, it is proposed the use of a new experimentally designed 7.62 mm calibre ammunition with a lighter weight (caseless-coreless). This can be used in carbine assault rifles with short barrel or pistols.... see more

Thermochemical exploration of mixing and combustion of parallel hydrogen injection into supersonic vitiated air stream in a divergent duct is presented. Three-dimensional Navier Stokes equations along with twoequation turbulence models and Eddy dissipatio... see more

El siguiente trabajo muestra un modelo numérico de un horno de recalentamiento tipo empujador, utilizando un programa comercial de dinámica de fluidos (CFD). El modelo acopla las ecuaciones de transferencia de calor, dinámica de fluidos y reacción química... see more

The investigation described in the present paper is concerned with the structure of atmospheric waves in the middle latitudes. The typical wave in the troposphere has, according to observational studies, a difference between the ... see more
