Rankine pōʻaiapuni mahu mīkini peahi uila

ʻOiaiʻanoʻenehana holomua ka loa e hoʻokēʻai ai, e hiki pinepine ike i ke kulana kahi o nā kumu i hoʻohana i kēia mea kanu i i loaa i loko o ka hope kenekulia. No ka laʻana, he Rankine kalapona, i i invented i loko o ka 19th kenekulia, ua hoʻohana 'ia i loko o ka mahu turbines a me ka manawa.

Ka nui inventor

Rankine kalapona i loaa ma ka Hawaiian physicist a me ka lunaʻenehana e noho ana, a hana i loko o ka umikumamaiwa kenekulia. Ka hana mea hou i hana muaʻole Ua kapaʻia i loko o ka hanohano o ke nä känaka 'epekema nui, ka mea i hoi i ke kākoʻo'-i hoʻokumu o iiaie oaoieei thermodynamics.

William John Rankin i hānau i loko o 1820 i loko o Edinburgh, kahi āna i aʻo i ka Institute no ka makahiki ekolu. Eia naʻe, e hoʻopau i kēia wahi i ke nä känaka 'epekema hiki ole no o ka mea pilikia kālā kulana. Akā, i i ole ia i ka manawaleʻa iā physicist hoʻokō i ka helu o ka maikaʻi kēia discoveries. No laila, i ka makahiki 1849, ua loaa na nā helu kaulike o thermodynamics, a wehewehe i ka pilina ma waena o ÿole mechanical ikehu a me ka wela. I lawe mai i ka hana o ka mahu-engine kumumanaʻo, a hoʻomohala i nā kumu mua walaʻauʻana i hana i ke kumu o ka hana ana i keia pa alima. Mau hoakaka ia lakou i ke kaʻina hana, i i haawiia mai i ka inoa i loko o ka hanohano o ke nä känaka 'epekema - Rankine pōʻaiapuni.

o ka Naauao

Kēia pōʻaiapuni o ka hana o kaʻimi naʻauao olelo o ka thermodynamic keʻano o ka hanaʻana lawe wahi iloko o ka mahu mana mea kanu ma ka repetition ano. E hiki ke hoomaopopo i na kumu o hana i komo i loko o kēia pōʻaiapuni:

• ka wai evaporates ma ka manaʻo koikoi kiʻekiʻe;
• Wai nā lātoma ma ka gaseous moku'āina e hoʻonui;
• pulu mahu condenses ma luna o nā paia o ka moku;
• loli puʻe ua mahuahua (hoi mai la i ka loiloi mua cia).

Ua hiki ke hoʻomaopopo i ka thermal ka hoʻokōʻana o kēia pōʻaiapuni mea pololei hapaʻauhau i ka loiloi mua ana wela. Nō hoʻi, i ka ka hoʻokōʻana o kēia kaʻina ua kena ae la ma ka puʻe a me thermal moku'āina o ke anakahi ma ka kūmole kulana a me ka mākeke.

mahu mīkini peahi uila

Kēia mokuna. He He wela engine, like me ka hopena o i uila mana ua ua loaʻa. I ka papa kuhikuhiE eiiiiiaiou o keia mea hoʻonoho hiki ke poe ma ke kēia papa:

• hoʻoneʻe loa, a he o ka epaepa huila a me ke kōmi i pili ia;
• he wahi lala ka eiiiiiaiou e like me kīʻamo a me ka stator.

mea hoʻonoho hana hiki ke wehewehe aku ma keia aoao. I ka wai i loko o ka gaseous moku'āina ma kiʻekiʻe ka mahana a me ka puʻe ua hanai aku i loko o ka mīkini peahi uila kīʻamo. Eia, ma supersonic māmā holo Loaʻaʻia ikehu transforms i loko o kinetic mau, ai ka paʻa o ke kipaku huna. Kēia, ma ka huli, i ka mea kinoea kahe i hana ma ka mīkini peahi uila maka. Kuapo o kēia mau kumu mua ke kumu o ka epaepa huila eʻoni aʻe, ma laila ka hana uila. E möakäka hou condensation o ka mahu, a ia kikiʻo i loko o ka kūikawā pa alima kapa i ka wai, mai ka wai catches i hou i loko o ka wela poe kuai. Pela, aia no he repetition o nā ana, e ua lawe mai Rankine pōʻaiapuni.

Keia rula ua hoʻohana 'ia i loko o nenoai ma nukelea mana mea kanu, e like me ka mea ua hoʻohana' ia i loko o ku-wale mīkini peahi uila huahelu no ka mana hanauna. Kēia noaia mea ma kahi loihi ka loa efficient a me ka hoʻokele waiwai. Mea kanu ke hoʻohana i nā loina o Rankine, haawi ma ka honua.
