Effects of radiative heat transfer on premixed spherically expanding NH3-air flames

This article numerically investigates the effects of radiation on the laminar burning velocity (LBV) extrapolated from microgravity spherical expanding NH 3 /air premixed flames, with equivalence ratios and pressures ranging from 0.7 to 1.3 and 1 to 50 atm, respectively. The simu...

Particle trapping in vortex crystals

We study the motion of inertial particles in two-dimensional inviscid and viscous vortex crystals, where vortices are placed at the tips of a regular polygon, and determine the conditions under which long-term trapping of particles can occur. In crystals with a central vortex, we...
