Fundamentals of Turbulent and Multiphase Combustion

Extension of the Eddy Dissipation Concept for turbulence/chemistry interactions to MILD combustion

“…Such a combustion regime is associated mainly with small-scale, high-intensity turbulence. In such a regime, u 0 ) S L and L 0 < d L , meaning that Kolmogorov scales are able to enter and to thicken the preheating zone and, possibly, the reaction region, leading to a thickened and distributed flame structure [35,36]. In such a scenario, it is appropriate to estimate the characteristic speed of the reacting fine structures from the turbulent flame speed.…”

Prediction of the Mechanical Erosion Rate Decrement for Carbon-Composite Nozzle by using the Nano-Size Additive Aluminum Particle

“…Graphite and the C-C composite nozzle wall undergo significant erosion due to impingement of Al(l)/Al 2 O 3 (l)-droplets at the convergent part of the nozzle [2]. For these reasons, the agglomeration phenomena need indepth understanding.…”

A Novel Methodology for Chemical Time Scale Evaluation with Detailed Chemical Reaction Kinetics

“…7 Additionally literature shows the non-premixed Damköhler number being calculated using τ I , and τ η the Kolmogorov mixing time which is the scale of the smallest eddies in the system where energy is dissipated to heat. 7 For gases the Batchelor scale τ B is equal to the Kolmogorov scale τ η , which is associated to the largest scales at which non-premixed streams remain segregated. 1 number, defined as is defined.…”

“…7 At this time a clear definition for τ c for complex chemistry systems involving detailed kinetic mechanisms is needed, and it is the focus of this work. In most cases a global chemistry assumption is made to simplify the estimation of τ c .…”
