(American Physical Society, 2005)In many applications a sustained, localized turbulent flow scours a cohesionless granular bed to form a pothole. Here we use similarity methods to derive a theoretical formula for the equilibrium depth of the pothole. ...

On nonlinear convection in mushy layers. Part 1: Oscillatory modes of convection. With Corrigendums (Cambridge University Press, 2002)We consider the problem of nonlinear convection in horizontal mushy layers during the solidification of binary alloys. We analyse the oscillatory modes of convection in the form of two and threedimensional travelling ...

(American Institute of Physics, 200410)In this work we investigate the dynamics of selfsustained detonation waves that have an embedded information boundary such that the dynamics is influenced only by a finite region adjacent to the lead shock. We introduce ...

(American Physical Society, 200411)We model the radial segregation patterns that form in a thin rotating drum partially filled with beads of two sizes. We predict that the waviness (or amplitudetowavelength ratio, denoted w) of a pattern should be subjected ...

(American Physical Society, 2003)We show that the structure of a dense, freesurface boundary layer granular flow is similar to the structure of a laminar liquid flow: There is a strong component of order (stratification parallel to the mean flow) ...

(American Physical Society, 2006)The classical experiments on turbulent friction in rough pipes were performed by Nikuradse in the 1930s. Seventy years later, they continue to defy theory. Here we model Nikuradse’s experiments using the phenomenological ...

(American Physical Society, 2002)When poured into a container, cohesive granular materials form lowdensity, open granular aggregates. If pressure is applied to these aggregates, they densify by particle rearrangement. Here we introduce experimental and ...
