Detailed simulation of LOX/GCH4 flame-vortex interaction in supercritical Taylor-Green flows with machine learning [PDF]
arXiv, 2023 Accurate and affordable simulation of supercritical reacting flow is of practical importance for developing advanced engine systems for liquid rockets, heavy-duty powertrains, and next-generation gas turbines. In this work, we present detailed numerical simulations of LOX/GCH4 flame-vortex interaction under supercritical conditions.

Environmental Progress &Sustainable Energy, EarlyView.Abstract Liquid fuels contain a large number of components. However, it is not computationally feasible to implement the detailed composition into numerical solvers in combustion chamber design. Surrogate mixtures are used to facilitate calculations, which can reproduce the fuel characteristics with fewer components providing reasonable accuracy ...

Energy Science &Engineering, EarlyView.Schematic approach of the green diesel production process and its utilization. ABSTRACT A unique green catalyst was derived from novel powdered Uzere tallow seeds shell calcined at 700°C for 1 h in a muffle furnace. The catalytic activity of the Uzere acidified catalyst was due to a high proportion of sulphur trioxide, calcium oxide, and potassium ...
