Density-wave fronts on the brink of wet granular condensation

Abstract Density-wave fronts in a vibrofluidized wet granular layer undergoing a gas-liquid-like transition are investigated experimentally.The threshold of quillingcard.com discount code the instability is governed by the amplitude of the vertical vibrations.Fronts, which are curved into a spiral shape, propagate coherently along the circular rim of the container with leading edges.They are stable beyond a critical distance from the container center.Based on an analysis of the emerging time and length scales, we propose a model for the pattern formation by maxbotix hrlv ez1 considering the competition between the time scale for the condensation of wet granular particles from a gas-like state and that of the energy injection resisting this process.
