International Scholarly Research Notices, Volume 2012, Issue 1, 2012., 2012 A one‐step, a two‐step, an abridged, a skeletal, and four detailed kinetic schemes of hydrogen oxidation have been tested. A new skeletal kinetic scheme of hydrogen oxidation has been developed. The CFD calculations were carried out using ANSYS CFX software. Ignition delay times and speeds of flames were derived from the computational results.

Understanding Kelvin-Helmholtz Instability in Paraffin-Based Hybrid Rocket Fuels [PDF]
, 2018 Liquefying fuels show higher regression rates than the classical polymeric ones. They are able to form, along their burning surface, a low viscosity and surface tension liquid layer, which can become unstable (Kelvin--Helmholtz instability) due to the ...
