Rapid shear of initially anisotropic turbulence in a rotating frame?
(2007)
In the present study, we investigate, using inviscid rapid distortion theory, the evolution of sheared turbulence in a rotating frame as a function of the rotation rate (including stable, transitional, and unstable regimes), ...
An analytical solution for rapidly distorted turbulent shear flow in a rotating frame
(2006)
In this study we apply rapid distortion theory to the case of nonstratified homogeneous turbulence that is sheared in a frame that counter-rotates at a rate that matches in magnitude the rotation associated with the mean ...
Numerical simulation of injection mold filling for semi-solid materials
(ASME, 1995)
Processing of metals and metal matrix composites in the semi-solid state is an emerging new technology and is becoming increasingly popular. This method provides several advantages over the traditional liquid state processing ...
Mathematical and computational modeling of die filling in semisolid metal processing
(1999)
A 'Bingham type', or Herschel-Bulkley constitutive relation capable of describing correctly the bulk behavior of the semisolid slurry is introduced. This relation is implemented in a modified version of the casting simulation ...
Transient planar squeeze flow of semi-concentrated fiber suspensions using the Dinh-Armstrong model
(2007)
Numerical simulations are undertaken for the transient squeeze flow between parallel plates under a constant load. The conservation equations are solved via the finite element method in space and the Crank-Nicolson method ...
