Mechanism of flame acceleration and detonation transition from the interaction of a supersonic turbulent flame with an obstruction
Willstrong Rakotoarison, Brian Maxwell, Andrzej Pekalski +1
The present paper seeks to determine the mechanism of flame acceleration and transition to detonation when a turbulent flame preceded by a shock interacts with a single obstruction…
Investigation of Turbulent Mixing and Local Reaction Rates on Deflagration to Detonation Transition in Methane-Oxygen
Brian Maxwell, Andrzej Pekalski, Matei Radulescu
In the current study, the influence of turbulent mixing and local reaction rates on deflagration to detonation transition (DDT) was investigated using a state-of-the-art large eddy…
Chapman-Jouguet deflagrations and their transition to detonation
Mohamed Saif, Wentian Wang, Andrzej Pekalski +2
We study experimentally fast flames and their transition to detonation in mixtures of methane, ethane, ethylene, acetylene, and propane mixtures with oxygen. Following the interact…
Role of detritus in a spatial food web model with diffusion
Andrzej Pękalski, Janusz Szwabiński
One of the central themes in modern ecology is the enduring debate on whether there is a relationship between the complexity of a biological community and its stability. In this pa…
How bad is to be slow-reacting ? On the effect of the delay in response to a changing environment on a population's survival
Ioana Bena, Michel Droz, Janusz Szwabinski +1
We consider a simple-model population, whose individuals react with a certain delay to temporal variations of their habitat. We investigate the impact of such a delayed-answer on t…
Risk of Population Extinction from Periodic and Abrupt Changes of Environment
Andrzej Pekalski, Marcel Ausloos
A simulation model of a population having internal (genetic) structure is presented. The population is subject to selection pressure coming from the environment which is the same i…
