... in the flow field (exit correction). As before, weak compressibility slightly affects the thickness swell (about 1% in the range of 0 ≤ B ≤ 0.02 ) mainly by a swell reduction, after which a substantial and monotonic increase occurs for B > 0.02 . The exit correction increases with increasing...

... coefficients, B and B sl , respectively. The pressures from the simulations have been used to compute the excess pressure losses in the flow field (exit correction). Weak compressibility slightly affects the thickness swell (about 1% in the range of simulations 0 ⩽ B ⩽ 0.02 ) mainly by a swell reduction, while...
