From: Towards uniformly oriented diatom frustule monolayers: Experimental and theoretical analyses
Simulated rising 2D diatom frustule and corresponding velocity field (unit m s−1) of surrounding water. The initial tilt angle (θ(0)) of both frustules was 30°. (a) The rising of a concave-up frustule. The frustule went through a self-adjusting process and eventually reoriented to a concave-down configuration. (b) The rising of a concave-down frustule. The tilt angle of the frustule oscillated between 29.9 and 32.6° throughout the process.
