Figure 1 3D Reconstruction and Measurement of VC Area Through Circular and Arc-Shaped Rigid Orifices

Panels A (circular orifice) and B (arc-shaped orifice) depict the long axis of flow in the sagittal and coronal view, with vena contracta (VC) short-axis area shown in the transverse view, and three-dimensional (3D) jet in the lower right panels. For each orifice shape used in the in vitro model, the transverse view demonstrates that the shape of the VC area is defined by the shape of orifice.
