AB - A two-dimensional model of staggered tube banks of the bristle pack with
different pitch ratios was solved by computational fluid dynamics (CFD). The
pressure distribution along the gap centerlines and bristle surfaces were studied
for different upstream pressure from 0.2 to 0.6MPa and models. The results
show that the pressure is exponentially rather than strictly linearly decreasing
distributed inside the bristle pack. The pressure distribution is symmetry about
the circle’s horizontal line. The most obvious pressure drop occurred from about
60º to 90º. There is no stationary state reached between the kinetic energy
and the static pressure when the upstream is larger than 0.3MPa.
