The two-dimensional circular geometry of the can
was generated in cartesian coordinates and mapped with
uniform rectangles, in the inner region, and different
sized trapezoids, in the outer region. Three different
equations were used to calculate the volume fraction
associated with each node: inner region, boundary region,
and intermediate region (Tattiyakul, 2001). Then,
the fraction of fluid volume having temperature in the
range of m to m þ 1 was integrated.
