(Cambridge University Press, 2006)We consider the problem of nonlinear oscillatory convection in a horizontal mushy layer rotating about a vertical axis. Under a neareutectic approximation and the limit of large farfield temperature, we determine 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 ...

(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. ...

(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 ...

(Cambridge University Press, 2006)The present effort documents the population trends of prograde and retrograde spanwise vortex cores in wall turbulence outside the buffer layer. Large ensembles of instantaneous velocity fields are acquired by particleimage ...

(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 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 ...

(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 ...

(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 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) ...

(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 ...

(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 ...

(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. ...
