... be caused by the assumptions of the chemical reaction. Hence, a new experiment is proposed to enhance the measurement accuracy and to investigate the reason of the disagreement. The authors propose a depressurized experiment and show the preliminary result of the experiment. It is found that a stable...

...Stefano d’Ambrosio; Ezio Spessa; Alberto Vassallo New computational procedures are proposed for evaluating the exhaust brake specific mass emissions of each pollutant species in internal combustion (IC) engines. The procedures start from the chemical reaction of fuel with combustion air and, based...

... simulation chemical reactions Pollutant emissions control and reduction has now become the principal marketing matter in industrial gas turbine field. During the last 15 years, the gas turbine device subjected to the most significant modifications was probably the combustion chamber. This fact...

... emissions. Because including detailed chemical reaction mechanisms for fuel oxidation and nitrogen chemistry into the CFD simulation was not feasible in the current framework, it was decided to simulate the reaction kinetics of the proposed combustion process regarding its ignition performance...

... loading and regeneration and to the soot mass accumulated in the trap. Carbon mass and energy balance through the regeneration process reveals that these phenomena cannot be attributed to chemical reactions in the trap. It is assumed that they are due to the effect of regeneration on the radial flow...

..., the potential for significant chemical reactions on a film-cooled surface is enhanced. Currently, there is little basis for understanding the effects on aero-performance and durability due to such secondary reactions. A shock tube experiment was employed to generate short duration, high temperature (1000–2800 K...

...N. Butuk; J.-P. Pemba This paper discusses an accurate numerical approach based on complex variables for the computation of the Jacobian matrix of complex chemical reaction mechanisms. The Jacobian matrix is required in the calculation of low dimensional manifolds during kinetic chemical mechanism...

... elementary chemical reactions. The model is able to take any type of inhomogeneities in the initial gas composition into account, such as inhomogeneities in the temperature field, in the air-fuel ratio or in the concentration of the recirculated exhaust gas. With this model the effect of temperature...
