Pressure Coefficient cP
on the suction (left) og pressure side (right) for Big Blade at an angle
of attack of 42,5º.
The physical model used in the CFD calculations are the
incompressible Euler equations. The computations results in force
coefficients for both blades on several angles of attack. These coefficients
is used to find the forces on the oares for varying flow speed. The
results show that the force coefficients are larger for Donald than for
Big Blade over the important initial movement from catch.
