We perform high-resolution numerical simulations of three-dimensional dynamics of an elongated bubble in a microchannel at moderate Reynolds numbers up to 1800. For this purpose, we use the coupled Brinkman penalization and volume of fluid methods im

In this work, we contribute to the development of numerical algorithms for the direct simulation of three-dimensional incompressible multiphase flows in the presence of multiple fluids and solids. The volume of fluid method is used for interface trac

Gaseous detonation propagation in a thin channel with regularly spaced cylindrical obstacles was investigated experimentally and numerically. The wave propagation with substantial velocity deficits is observed and the details of its propagation mecha

In this work, we analyze numerically the dynamics of one-dimensional gaseous detonations propagating in a mixture with periodically varying properties such as density, temperature, or mixture composition. It is found that periodic upstream variations

In this work we analyze, within the framework of the reactive Burgers model (Kasimov et al., 2013), the propagation of detonation in a periodically varying medium. We investigate the role of the amplitude and the wavelength of the variations on the d

We consider a one-dimensional gaseous detonation wave propagating in a channel with a spatially periodic friction factor with the purpose of understanding how non-uniform momentum losses affect the detonation dynamics. The problem is investigated by

PROGRESS IN DETONATION RESEARCH.
In recent work [1], the analog Burgers model of detonation [2] was used in order to explore how detonation propagates in a medium with periodically varying reactivity.

We use numerical simulations of the reactive Euler equations to analyse the nonlinear stability of steady-state one-dimensional solutions for gaseous detonations in the presence of both momentum and heat losses. Our results point to a possible stabil
