The present paper compares full kinetics mechanisms in numerical modelling of porous radiant burners (PRB), with their reduced forms. The two most frequently used mechanisms of methane combustion (GRI3.0 and Miller) were selected and their effects were examined on temperature, species concentration, burning speed, and pollutant emission. While the findings of numerical simulation of PRB sho...

A New Static Var Generator (SVG), using cascaded full-bridge inverters (FBI) with binary output levels and the parallel connections of two cascaded inverters by means of current sharing reactor in each phases is introduced. The new M-level inverter, where M is 2n+2 - 3, consists of only 2n single-phase full bridges for each phases. The proposed technique not only increases the current capacity ...

Due to the network technology advances, an order-of-magnitude jump has been produced in the network bandwidth. This fact has returned to wake up the interest on protocol offloading, since network communication is a key factor for system performance. Thus, much research work on offloading is been done, particularly on TCP offloading as it has been the main transport protocol for many years, and ...

A new hybrid kinetic electron model is developed for electrostatic full-f gyrokinetic simulations. The model is verified by computing the neoclassical transport and the linear ion temperature gradient driven trapped electron mode (ITG-TEM) stability. Impacts of kinetic electrons on the ITG turbulence are investigated, and a new saturation mechanism due to corrugated density profiles, which are ...

A status report is made of an on-going full QCD study on the CP-PACS aiming at a comparative analysis of the effects of improving gauge and quark actions on hadronic quantities and static quark potential. Simulations are made for four action combinations, the plaquette or an RG-improved action for gluons and the Wilson or SWclover action for quarks, at a ≈ 1.1-1.3GeV and mπ/mρ ≈ 0.7-0.9. Result...

Most lattice Quantum Chromodynamics (QCD) formulations explicitly break chiral symmetry. This leads to unwanted mixing between operators of different chiral sectors, exceptional configurations when the simulated quark masses approach their physical values, and no clear definition of a topological index. The overlap Dirac operator solves these problems by satisfying a lattice variant of chiral s...

In this paper we will give a brief overview of the physical modeling language Modelica, present the modeling and simulation environment MathModelica, and describe some industrial projects where MathModelica has been used.
