Influence of pH and Carbonate Buffering on the Performance of a Lactate Microbial Fuel Cell
Microbia Fuel Cells (MFC’s) are complex environments where electrochemical, physical and biological aspects must be considered together. In this work we present a 1D model partially describing a Shewanella oneidensis MFC that degrade sodium lactate [lactate -> Acetate + CO2 + 2H+ + 2e-]. ... Mehr lesen
Mechanical Behaviour of TiAl Spherical Particles Including Friction Effect
Powder metallurgy is a key technology for manufacturing advanced components based on TiAl alloys. Cold compaction is the primary step to produce green parts. Cold deformation of TiAl powder is difficult due to its typical poor ductility. Plastic deformation and cracking susceptibility of ... Mehr lesen

Finite Element Approach for Optimizing the Cooling of the Metallic Bipolar plates for Fuel Cell Applications
Metallic bipolar plates promise several advantages for fuel cell applications. On the other hand, cooling of these plates is a critical task regarding design optimization. The high thermal conductivity of the material and the complex geometry of these plates affect directly the cooling ... Mehr lesen
Aerodynamic Study For Air To Gas Leakage Reduction In A Typical Rotary Regenerative Air Preheater Of Coal-Fired Steam Generators
The present study relates to the reduction of the amount of air to gas leakage in a typical rotary regenerative air preheater of coal-fired steam generators, by means of computational thermo-fluid-dynamics. Due to the gaps, or clearances, required for rotation, there is a significant ... Mehr lesen
Modeling of High Temperature Superconducting Tapes, Arrays and AC Cables Using COMSOL
In this paper we present a set of numerical models created with COMSOL Multiphysics. The set includes quantitative models of a superconducting tape operated at 77 Kelvin, carrying a transport current and exposed to external magnetic field; an array of such tapes and a triaxial high ... Mehr lesen
Model of an Interdigitated Microsensor to Detect and Quantify Cells Flowing in a Test Chamber
Microfabricated planar interdigitated electrodes can detect and analyze cells or particles giving an impedance-based characterization. This method presents several advantages: real-time detection, label-free analysis, non-invasive sensing, easiness of integration and high-throughput ... Mehr lesen
Flow Induced Oscillations of Marine Risers with Wake Interference
With offshore oil and gas exploration and production moving into ever deeper waters, the suspended length of marine risers (transporting hydrocarbons from the seabed to the surface) can easily exceed 3000 meters. One of the major design requirements for risers in (ultra) deep water is to ... Mehr lesen
Identification of the Complex Moduli of Orthotropic Materials using Modal Analysis
It is very difficult to measure the global properties of heterogeneous and anisotropic materials like composites and sandwich structures. When designing composite sandwich applications, the elastic properties are required to perform structural stiffness and strength calculations. ... Mehr lesen
