Ballistic Deposition at Glancing Angles
This is an older project for which there is no published work, but the
pictures are quite cool! Shown are snapshots of the evolution of a growing
surface when particles are ballistically incident at angles of +7.125 or
-7.125 degrees (arctan(1/8)) from the horizontal and stick irreversibly to
the deposit upon first contact. Somewhat paradoxically, glancing angle
incidence leads to a coarsening array of nearly vertical fingers. The
surface is shown after 2 million, 10 million, and 50 million particles have
been deposited. The number of particles displayed is 100,000 for these three
cases, with different colors for each 20% of the deposit.
