—While studying fluid dynamics, a particular
experiment aroused the authors’ interest. The experiment is
about the attachment of a light sheet of paper to a wide disk of
which the center of it is connected to a straw that the
experiment performer blows their breath in. This experiment,
at a macro level, shows quite a simple result; the paper sticks to
the disk against the pressure of exhaled air. At a micro level,
however, it shows comparatively complicated result than at the
macro level; the sheet of paper inevitably oscillates with a
certain period. This phenomenon has not analyzed by any other
researchers. On this paper, this phenomenon, which is named as
“Fluid-Epsilon Oscillation”, is analyzed with simple harmonic
motion. Considering of the practical use of the fluid-epsilon
oscillation, electromagnetic induction caught authors’ mind.
Applied to fast moving vehicles, this phenomenon is anticipated
to be an efficient solution to the imminent issue of the energy
exhaustion. In an attempt to apply the phenomenon to
computer science, the authors created a program that calculates
the period of the oscillation.
