DOI: 10.1016/j.combustflame.2020.12.012
Abstract: Abstract Numerical simulations of one-dimensional pulsating detonation in off-stoichiometric n-heptane/air mixtures are conducted by solving the reactive Navier–Stokes equations with a skeletal chemical mechanism. The effects of mixture equivalence ratio, initial pressure and temperature on… read more here.

DOI: 10.1016/j.combustflame.2021.02.031
Abstract: Abstract Direct Numerical Simulations (DNS) are performed to investigate the process of spontaneous ignition of hydrogen flames at laminar, turbulent, adiabatic and non-adiabatic conditions. Mixtures of hydrogen and vitiated air at temperatures representing gas-turbine reheat… read more here.

Abstract: Reaction fronts described by the Kuramoto-Sivashinsky (KS) equation can exhibit complex behavior as they separate reacted from unreacted fluids. If the fluid of higher density is above a fluid of lower density, then the Rayleigh-Taylor… read more here.

DOI: 10.3390/ma15103525
Abstract: This paper studies the go- and -stop movement of a receding reaction front (RF) during a discontinuous dissolution (DD) process. A special simulation procedure was applied for the DD reaction to predict a jerky motion… read more here.
