The more convergenceAngle increases, the greater dynamic pressure, static pressure and total pressure rise.
当合流角增加时,动压、静压、全压均会增大,且角度越大增幅越明显。

Conclusions FC method for measuring ERO with feasibility in aortic regurgitation with a flat proximal flow convergenceAngle, provides a reliable approach to quantify aortic regurgitation.
Principes and some Suggestions are proposed that should be followed when a convergence or divergence diffuser is used in design. The method selecting the wall slope Angle is provided.
