<p>An objective of the present invention is to allow low processing load predictions of adhesion forecast regions of dust particles. Provided is an adhesion forecast region estimation device (1), comprising: a singularity/singularity line detection unit (11), which computes singularities such as vortices or nodes by a singularity theorem, based on velocity vector data, and thereby computes singularity lines such as adhesion points, detachment points, or adhesion lines and detachment lines; and a detached bubble region detection unit (12), which detects detached bubble regions from the singularity lines, etc. Or, provided is an adhesion forecast region estimation device (1), comprising: a singularity/singularity line detection unit (11), which detects singularity lines from envelopes of surface streamlines which are the results of the integration of surface velocity vector data; and a detached bubble region detection unit (12), which detects detached bubble regions from fluid streamlines which are the results of the integration of fluid velocity vectors from a given point.</p> |
