Separator for Cleaning of Fuel Fluid from Contamination or Microbial in Conditions of Microgravity

Abstract

The paper presents the developed separator
for cleaning fluid fuel from contaminants
and microorganisms using the above of the
surface of fluid air in a tank with fluid fuel.
The above of the surface of fluid air in a
tank with fluid fuel under conditions of
decreasing gravitational acceleration, turns
into an air bubble and, due to its released
surface energy, moves from the upper
position to the bottom of the tank, fixing
microparticles of contaminant or cells of
microorganisms, contained in a fluid, on its
surface. The air bubble reaching the bottom
of the tank reflects from it and begins to
move in the opposite direction, upon
reaching of the top of the tank, it is
separated from the total volume of fluid fuel
in the tank by a flap. Strong fixation of
microparticles of contaminants and cells of
microorganisms on the moving bubble is
due to the multiple increase of the role of
the surface tension force under these
conditions. The developed separator
permitted to clean microparticles of
contaminants and microorganisms from
fluid in conditions of microgravity simply
and highly effective.
