(American Institute of Physics, 200101)When a solid sphere impacts on a deep layer of granular medium, it generates an ejecta sheet and a transient axisymmetric crater. The gravitydriven radial collapse of this crater generates a pressure spike, as the cavity ...

(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 ...

(Cambridge University Press, 2002)We investigate hydrodynamic instability of a steady planar detonation wave propagating in a circular tube to threedimensional linear perturbations, using the normal mode approach. Spinning instability is identified and ...

(American Institute of Physics, 2002)A theory of stationary particle size distributions in coagulating systems with particle injection at small sizes is constructed. The size distributions have the form of power laws. Under rather general assumptions, the ...

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 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) ...

(Cambridge University Press, 2003)Spanwise structure and growth mechanisms in a turbulent boundary layer are investigated experimentally. PIV measurements are obtained in the streamwise– spanwise (x–z)plane from the buffer layer to the top of the ...

(American Institute of Physics, 200311)A direct numerical simulation ~DNS! is used to study the effect of a freestream isotropic turbulent flow on the drag and lift forces on a spherical particle. The particle diameter is about 1.5–10 times the Kolmogorov ...

(American Institute of Physics, 20031222)We use a continuum model to investigate the isochoric axial contraction and expansion of a right circular cylindrical specimen composed of a nematic elastomer that is crosslinked in a uniaxial state and then annealed. ...

(Cambridge University Press, 2004)This paper presents part 2 of a study of nonlinear convection in horizontal mushy layers during the solidification of binary alloys. Part 1 dealt with only the oscillatory modes of convection (Riahi, J. Fluid Mech. vol. ...

(Cambridge University Press, 2004)The interaction of an isolated spherical particle with an isotropic turbulent flow is considered using direct numerical simulations (DNS). The particle Reynolds number is varied from about 50 to 600 and the particle ...

(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 ...

(Society of Industrial and Applied Mathematics, 2005)A steady planar selfsustained detonation has a sonic surface in the reaction zone that resides behind the lead shock. In this work we address the problem of generalizing sonic conditions for a threedimensional unsteady ...

(Cambridge University Press, 2005)We perform direct numerical simulations of a rigid sphere translating parallel to a flat wall in an otherwise quiescent ambient fluid. A spectral element method is employed to perform the simulations with high accuracy. ...

(American Institute of Physics, 2005)Deformation mechanisms involving mass transport by stress driven diffusion influence a large number of technological problems. We study the formation of undulations on surfaces of stressed films at high temperature by ...

(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. ...

(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 ...
