ʻO ka hoʻohālike ʻana i nā waiwai o ka media porous e pili ana i nā ʻenehana makemakika paʻakikī a me ka helu helu. Hiki i kēia mau hiʻohiʻona mai nā simulation pore-scale, e hopu ana i ka kikoʻī kikoʻī o ka pūnaewele pore, i nā hiʻohiʻona continuum e wehewehe ana i ka ʻano awelika ma luna o ka leo nui.

11. He aha kekahi mau pilikia i ka hana ʻana me nā media porous?

Pili pinepine nā pilikia me ka porous media i ke ʻano a me ka wānana ʻana i kā lākou ʻano ma lalo o nā kūlana like ʻole. No ka laʻana, ʻo ka hoʻoholo pololei ʻana i ka hāʻawi ʻana i ka nui o ka pore a i ʻole ka hoʻomaopopo ʻana i ke ʻano o ka hoʻololi ʻana o ka hoʻololi ʻana i ka media e paʻakikī ke kahe wai. Eia kekahi, i ka wā e pili ana i nā media porous maoli e like me nā pōhaku a i ʻole ka lepo, hoʻohui ko lākou heterogeneity i kahi papa o ka paʻakikī.

12. He aha kekahi mau kuhikuhi e hiki mai ana i ka noiʻi porous media?

ʻO nā kuhikuhi i ka wā e hiki mai ana i ka noiʻi media porous he ākea a interdisciplinary. Hoʻopili lākou i ka hoʻomohala ʻana i nā mea hou me ka porosity i hoʻopaʻa ʻia no nā noi kikoʻī, e hoʻonui i ko mākou ʻike i nā hanana kaʻa i nā ʻōnaehana porous, a me ka hoʻomaikaʻi ʻana i kā mākou hiki ke hoʻohālike. ʻO nā wahi noiʻi e like me nā mea porous nanoscale a me nā hale porous bio-inspired ke loaʻa nei ka traction, e wehe ana i nā palena hou no ka ʻike a me ka hana hou.

I loko o ka honua e ulu nei o ka porous media, ʻo ia kekahi o nā nīnau i nīnau pinepine ʻia. Eia naʻe, ʻaʻole pau ka ʻimi ʻike ma ʻaneʻi. Ke hoʻomau nei nā ʻepekema a me nā ʻenekinia i ka ʻimi ʻana i kēia kahua hoihoi, ua hoʻohiki ka wā e hiki mai ana i ka waiwai o nā ʻike hou, ʻenehana, a me nā noi e ʻimi.

Makemake ʻoe e ʻimi i ka honua o ka porous media?

Inā ʻoe e ʻimi nei i nā mea kiʻekiʻe no kāu papahana, e kūkākūkā ana no kāu noiʻi, a i ʻole maʻalahi

makemake nui e kūkākūkā i ka hiki o ka porous media, eia mākou e kōkua. HENGKO, me kā mākou ʻike waiwai

a me ka hoʻokō ʻana i ka hana hou ma ka media porous, hoʻokipa iā ʻoe e hele aku.

Mai hoʻokaʻulua e kuhikuhi i kāu mau nīnau, manaʻo, a me nā manaʻo ika@hengko.com.

E luʻu pū kākou i loko o ka honua hoihoi o ka porous media, a ʻike pehea e hiki ai iā mākou

hoʻoikaika i ka holomua a hana i nā hāʻina no ka wā e hiki mai ana. E kiʻi mai i kēia lā!
