Interactions of mildly irregular detonation waves with sharp interfaces separating combustible mixtures from an inert gas were modeled numerically using the compressible linear eddy model for a large simulation (CLEM-LES) approach. In recent experiments Lieberman and Shepherd [“Detonation interaction interface,” Phys. Fluids 19, 096101 (2007)], such interactions resulted in transmitted shock-tu...

Recent experiments on ultracold non-reactive dipolar molecules have observed high two-body losses, even though these can undergo neither inelastic, nor reactive (as they are in their absolute ground state), light-assisted collisions (if measured the dark). In presence of an electric field losses seem to be near universal (the probability loss at short-range is unity) while absence it non-univer...

The conditional filtering method is proposed as a subfilter combustion model for large-eddy simulation LES of turbulent nonpremixed combustion. The novel method is based on conditional filtering of a reactive scalar field and an extension of conditional moment closure CMC for LES. Filtering conditioned on isosurfaces of the mixture fraction is adopted to resolve small-scale mixing and chemical ...

Vitrimers constitute a new class of covalent adaptable networks (CANs), in which thermally stimulated associative exchange reactions allow the topological rearrangement dynamic network while keeping number bonds and crosslink density constant. The current study proposed solvent-free method to synthesize vitrimers by reactive melt mixing using commercial biobased/biodegradable polyester, poly(bu...

Oxy-fuel combustion is a promising strategy to minimize the environmental impact of combustion-based energy conversion. Simple and flexible tools are required facilitate successful integration such strategies at industrial level. This study couples measured residence time distribution with chemical reactor network analysis in close-to-reality combustor. provides detailed knowledge about various...

Flows can modify the eeects of nonlinear reactions. Here we use a lattice Boltz-mann method to simulate an athermal ow which advects reactant species. As an example we consider a reactive system modeled by the Brusselator which exhibits Turing structures; the system is subjected to mixing as induced by the wakes behind obstacles. The resulting eeect is a modiication of the reaction patterns whi...
