He mea hana mīkini ka mea hoʻohuihui pauka i hoʻohana ʻia e hoʻohuihui like i nā mea pauka like ʻole. Hoʻokumu ʻia kona kumu hana ma nā ʻano hana hoʻohuihui kumu e like me ke kāwili ʻana o ka convection, ka kāwili ʻana o ka shear, a me ka kāwili ʻana o ka diffusion, e hiki ai i nā mea ke hoʻokō i ka hui wikiwiki a like i loko o ka manawa pōkole.
Ua laha ka hoʻohuihui ʻana o nā mea pauka i ka hana ʻoihana, e lilo ia i ʻāpana koʻikoʻi o ke kaʻina hana. No ka laʻana, i ka hana ʻana i ka meaʻai, nā mea hoʻouluulu mahiʻai, nā lāʻau lapaʻau, a me nā kemika o kēlā me kēia lā, pono e hui like ʻia nā mea o nā ʻano like ʻole ma kahi ʻāpana i manaʻo ʻia ma mua o ka hana ʻana e loaʻa ai ka huahana hope loa. I ka wā o ka hana ʻana, pili pololei ka like ʻana o ka hoʻolaha ʻana o ka pauka i ka huahana hope loa.
ʻO ke kāwili ʻana i nā mea e pili ana i ke kaʻina hana neʻe paʻakikī kahi e loli ai ke kūlana a me ka wikiwiki o ʻelua a ʻoi aku paha mau ʻāpana ma lalo o ka mana o nā mana o waho (nā mana mechanical a i ʻole ke umekaumaha), e hopena ana i ka noho pū ʻana o nā ʻāpana he nui ma o ka neʻe pili a me ke komo like ʻana i loko o kā lākou mau ʻāpana ʻāpana. ʻO kēia kaʻina hana e alakaʻi ai i kahi hoʻolaha like o nā ʻāpana like ʻole. Ma muli o ka hoʻomau macroscopic a me ka microscopic discreteness o nā ʻāpana, ʻo ka neʻe ʻana o nā ʻāpana me nā waiwai like ʻole e hōʻike ana i kahi kaʻina hana chaotic paʻakikī loa.
ʻO ke kāwili ʻana i ka pauka maloʻo e pili ana i ke kaʻina hana o ka kāwili like ʻana i ʻelua a ʻoi aku paha mau pauka maloʻo e hōʻoia i ka hoʻolaha like ʻana o kēlā me kēia ʻāpana. Hoʻohana nui ʻia kēia ʻenehana i: ka ʻoihana meaʻai (palaoa, nā mea ʻala, nā pauka inu, nā premixes, a pēlā aku), ka ʻoihana lāʻau lapaʻau (ke kāwili ʻana i nā mea hana a me nā excipients), ka ʻoihana kemika (nā mea hoʻouluulu, nā mea holoi, nā mea maka plastik, a pēlā aku), a me ka ʻoihana hānai (ke kāwili ʻana i nā palaoa, nā huaora, a me nā minelala).
ʻO ka hui ʻana o ka pauka e hilinaʻi pinepine ʻia i ka hana synergistic o ʻekolu mau kaʻina hana: convection, shearing, a me diffusion.
ʻO ka hoʻohuihui convective e pili ana i ka neʻe nui ʻana o nā ʻāpana pauka. Ma lalo o ka mana o nā mana o waho, hele nā ʻāpana pauka i ka convection e like me ka wai, e neʻe ana mai kekahi wahi a i kekahi, e hoʻokō ana i ka hoʻolaha like ʻana ma luna o kahi ākea.
ʻO ke kāwili ʻana i ka ʻoki ʻana e pili ana i ka ʻoki ʻana i loko o nā puʻupuʻu pauka. Ma lalo o ka mana o nā mana o waho, paheʻe nā ʻāpana pauka kekahi i kekahi, e hana ana i kekahi mau ʻili paheʻe i loko o ka mea. Hoʻohuihui kēia mau ʻili a hui pū e like me nā papa lahilahi o ka wai, e ʻoki mau ana i ka pauka e hoʻokō i ka hoʻolaha like ʻana ma nā wahi kūloko.
ʻO ka hoʻohuihui ʻana i ka hoʻolaha ʻana he hana hoʻohuihui kūloko ma waena o ʻelua mau ʻāpana e pili kokoke ana ma ka pae microscopic. Ma muli o nā loli i nā kūlana pili o nā ʻāpana e pili kokoke ana, hana ʻia ka interpenetration a me ka hoʻohuihui ʻana, e ʻae ana i ka mea e hoʻokō i kahi hui like loa.
Hiki ke hoʻokaʻawale ʻia ke kaʻina hana kāwili ʻana i ʻekolu mau pae: kāwili convective, kahi pae e pili ana i ka convection a me ka shear, a me ka kāwili diffusion.
Pae 1: ʻO kēia pae e pili ana i ka hui ʻana o ka convective, me ka wikiwiki o ka hui ʻana.
Pae 2: Pili kēia pae i nā hopena i hui pū ʻia o ka convection a me ka shear, e hopena ana i kahi manawa hui lōʻihi.
Pae 3: ʻO kēia ke kahua hoʻohuihui diffusion, kahi e kūlike ai ka hui ʻana ma waena o ka hui ʻana a me ka hoʻokaʻawale ʻana, me ke kekelē o ka homogeneity e loli ana a puni kahi waiwai.
