![]() ![]() Markstein length was influenced significantly by an increase in pressure than temperature due to a substantial reduction in flame thickness. The local flame equivalence ratio estimated from the simulated reactant species profiles shot up by 15% than the global equivalence ratio for preferentially unstable mixtures. The capability of existing Lewis number models to predict the transition was examined, and the BM model showed excellent agreement with all experiments. The flame stability analysis of all experiments emphasized that a transition of stable to unstable flame occurred at ϕ = 1.4 due to preferential diffusion effects. The present work aimed to measure the unstretched LBV and burned gas Markstein length of premixed n-dodecane-air mixtures at pressure = 1–4 bar, temperature = 400–450 K, and ϕ = 0.8–1.4. ![]() Therefore, it is essential to have a precise reaction mechanism to predict the combustion characteristics such as laminar burning velocity (LBV) and ignition delay times of individual components and the surrogate. The choice of a surrogate combination to estimate the combustion characteristics of a complex fuel depends strongly on its individual component’s combustion properties, and its physical and chemical properties. How is it bottom of the barrel diesel costs so much? It's the law! written by idiots and crooks.N-Dodecane is an important representative in several surrogates of multicomponent fuels like gasoline and jet fuels. "Sustainability" means you pay for it big time but don't have a right to receive it. Enviro-whinerism has carefully lowered the energy content/gallon. The most recently built refinery is ancient. Government intervention tortures your access to liquid fuels. $$\ce$-cut and up is cheap diesel and kerosene, with maximum cetane number. ![]() Cracking produces smaller molecules - alkanes, and alkenes. If we have a long-chain hydrocarbon, such as decane, and we split it through thermal cracking (say in an industrial plant), we use high temperatures, and high pressures. ![]()
