Kinetic theory and boundary conditions for flows of highly inelastic spheres. Quarterly progress report, July 1, 1994--September 30, 1994
In the last quarter, we focused on steady, fully developed, gravity-driven flows of identical, smooth spheres down bumpy inclines, with flow depths greater than one particle diameter, solid fraction profiles everywhere less than .65, and dimensionless granular temperature T(y={beta}) at the top between 0 and 10. For prescribed boundary bumpiness (r=l and {delta}=.414), restitution coefficients of the boundary (e{sub w}=.5) and the flow particles (e=.5), and angles of inclination ({phi}0=25.5{degrees}, 27.505{degrees}, 28{degrees} and 34{degrees}), we determined what appeared to be complete range of T(y={beta}) (within 0
