Ua noʻonoʻo kēia ala i nā ʻano hana hemahema maʻamau no nā mea palupalu, a ua hoʻohana i ka Finite Element Analysis e hoʻoholo i nā ukana hana ma ka nozzle me ka kikoʻī. Ua hoʻohana ka hoʻolālā i nā ʻāpana sapphire me nā geometries maʻalahi e kaomi i kahi ʻāpana nozzle acrylic i mea e hōʻemi ai i nā koʻikoʻi tensile ma nā ʻaoʻao o loko o ka ʻāpana kahi i kau ʻia ai ke kaomi mai ka wahie. No ka mana paʻi i hāʻawi ʻia, ʻoi aku ke kumukūʻai o kēia hoʻolālā ma mua o ka mea i hana ʻia mai ka sapphire wale nō a ʻoi aku ka lōʻihi ma mua o ka mea i hana ʻia me ka acrylic wale nō.

ʻO ka cavitation i loko o nā puka i hōʻike ʻia i ka hilinaʻi ʻana i ka geometry, ʻo ia hoʻi ma ke kihi inclination o ke axis waena o ka puka. ʻOiai ua ʻike ʻia ka cavitation ma nā ʻaoʻao ʻelua o ka puka me ka ʻoki ʻoi aku ka nui, ʻaʻole ia ma muli o ka cavitation string, ʻo ia ka mea i manaʻo nui ʻia ka cavitation ma kēia wahi i nā haʻawina i hala.

ʻO ka hana e hiki mai ana e wehe i nā puka hoʻomaʻemaʻe mai nā koʻi sapphire, a ma kahi o ka hoʻohana ʻana i nā ʻāpana sapphire maʻalahi i kau ʻia i loko o nā ʻili kila kila. Manaʻo ʻia kēia hoʻololi e hōʻemi i ke koʻikoʻi koʻikoʻi i loko o nā ʻāpana sapphire a ʻae i nā ikaika hoʻopaʻa ʻoi aku ka nui ma mua o ka hiki me ka hoʻolālā mua.

E hoʻāʻo ʻia nā ʻāpana hou e hōʻoia i kā lākou hana a laila e hana ʻia nā hoʻokolohua ma luna o kahi ʻano o nā puʻe hope (cavitation umbers) i loko o kahi keʻena kaomi. E hoʻopuka kēia i kahi ʻano o nā kahe cavitating no ke aʻo hou ʻana.

Makemake nā mea kākau e hoʻomaikaʻi i ka EU no ke kākoʻo ʻana i kēia hana ma lalo o ka papahana HERCULES-C, a mahalo pū i ka Swedish Energy Agency no kā lākou kākoʻo.
