Efficiently Generating Mixing by Combining Differing Small Amplitude Helical Geometries
Helical geometries have been used in recent years to form cardiovascular prostheses such as stents and shunts. The helical geometry has been found to induce swirling flow, promoting in-plane mixing. This is hypothesised to...
