	%X In this paper, the 2-D unsteady viscous flow around
two cam shaped cylinders in tandem arrangement is numerically
simulated in order to study the characteristics of the flow in turbulent
regimes. The investigation covers the effects of high subcritical and
supercritical Reynolds numbers and L/D ratio on total drag
coefficient. The equivalent diameter of cylinders is 27.6 mm The
space between center to center of two cam shaped cylinders is define
as longitudinal pitch ratio and it varies in range of 1.5< L/D<6.
Reynolds number base on equivalent circular cylinder varies in range
of 27×103< Re <166×103 Results show that drag coefficient of both
cylinders depends on pitch ratio. However, drag coefficient of
downstream cylinder is more dependent on the pitch ratio.
