Early Stages of Flame Propagation in Tubes with No-slip Walls and the Mechanism of Tulip Flame Formation
Chengeng Qian, Cheng Wang, Michael A. Liberman
The early stages of flames propagation in tubes with no-slip walls and the inversion of the flame front from a convex shape directed towards unburned gas to a concave shape with a…
The Pencil Code, a modular MPI code for partial differential equations and particles: multipurpose and multiuser-maintained
A. Brandenburg, A. Johansen, P. A. Bourdin +34
The Pencil Code is a highly modular physics-oriented simulation code that can be adapted to a wide range of applications. It is primarily designed to solve partial differential equ…
Convergence properties of detonation simulations
Chengeng Qian, Cheng Wang, JianNan Liu +3
We present a high-resolution convergence study of detonation initiated by a temperature gradient in a stoichiometric hydrogen-oxygen mixture using the Pencil Code and compare with…
Influence of chemical kinetics on detonation initiating by temperature gradients in methane/air
Cheng Wang, Chengeng Qian, JianNan Liu +1
Different simplified and detailed chemical models and their impact on simulations of combustion regimes initiating by the initial temperature gradient in methane/air mixtures are s…
Influence of chemical kinetics on spontaneous waves and detonation initiation in highly reactive and low reactive mixtures
Mikhail Liberman, Cheng Wang, Chengeng Qian +1
Understanding the mechanisms of explosions is important for minimizing devastating hazards. Due to the complexity of real chemistry, a single-step reaction mechanism is usually use…
