Dariel gives presentation.
Thomas' notes:-
- Segregation strength plot: would look better with x-axis log
...
- ; should have segregation strength 0 at AR=1
...
- Clarify labels 1=spheres 2=elongated
...
- averaging region is very deep
...
- ; data. like kinetic stress should not be averaged over inhomogeneous regions
- density fraction: some asymmetry in x
- Observation: spheres always have higher kinetic stress ratio (s_k^1/s_k) than 0.5, even higher than (rho^1/rho), ratio is increasing with more extreme AR
...
- . But: you are averaging over inhomogeneous region in z
...
- d_z=1 characteristic axis perpendicular to surface, d_z
...
- increases with AZ more extreme
...
- Ant notes upcoming paper comparing volume vs shape segregation
...
- , and paper with Mueller Christoph
- A_eff: uses average angle
...
- , thus not accurate; better integrate over psd.
Goal of the paper:-
- First show that s_k^1/s_k>phi^1/phi independent of AR
...
- Then show R_eff=f(AR), and R_eff=R_sphere=1 are the transition points
Next steps:-
- Plot R_eff=f(AR) for all AR
...
- Compare with the Hill Tan theory (see Deepak's paper) by looking at s_k^1/s_k and s_c^1/s_c vs phi^1/phi (using non-averaged values)
...
- . Use local values, not averages over big regions
- problem: s_c cannot be computed b/c of nan's. THis is likely b/c SuperQuadricParticle::getInteractionWith does return an interaction if the radii overlap, not if the particles are in contace
