I. IiNgcebiso eziSisiseko kunye neFilosofi yoYilo
I-Spiral-ityhubhu yokutshintshiselana ngobushushu sisixhobo sokutshintshiselana kobushushu esenziwe ngokujiya kobushushu{1}}iityhubhu zokutshintshela kubumbeko olujikelezayo olunomlinganiselo othile kunye neradiyasi yokugoba; ulwelo olushushu nolubandayo luhamba kwityhubhu nakwicala leqokobhe, ngokulandelelanayo, litshintshisa ubushushu kwiindonga zetyhubhu.
·Imbono engundoqo yoyilo kukuphucula ukusebenza kobushushu xa uwonke ngaphakathi kwendawo enyiniweyo ngokwandisa kwangaxeshanye iindlela zokuhamba, ukonyusa isiphithiphithi solwelo, kunye nokwandisa ukuxinana kwendawo yokutshintsha ubushushu.
Xa kuthelekiswa noyilo lwemveli oluthe ngqo{0}} lwetyhubhu, ubume be-spiral bongeza ngokubonakalayo umthamo wogqithiso lobushushu ngokwevolumu yeyunithi nganye ngaphandle kokunyusa kakhulu ubungakanani besixhobo sisonke, sisenze sixabiseke kakhulu{1}}kukusebenza kakuhle, iinkqubo zogcino{2}}zamandla.
II. Imigaqo yoYilo lokuTshintshela ubushushu
Inkqubo yokudlulisa ubushushu kwiSpiral-iityhubhu ezitshintshiselana ngobushushu isabambelele kwiindlela zakudala zokuqhuba ubushushu kunye nokudluliselwa kobushushu{1}}apho ubushushu buqhutywa ngodonga lwetyhubhu kwaye buthwalwe kukuhanjiswa kwamanzi ashushu nabandayo{2}}kodwa inzuzo yawo engundoqo isekukomelezeni okubalulekileyo kokudluliselwa kobushushu.
.
·Njengoko ulwelo luhamba kwityhubhu ejikelezayo, igophe liphembelela amandla asecentrifugal atshintsha iprofayile yesantya, evelisa ukuqukuqela kwesibini okunqamlezayo (i-Dean vortices); esi sakhiwo sokuhamba ngokuqhubekayo sihlahlela udonga lwetyhubhu, luphazamisa umda womda we-thermal.
Ukucuthwa okuqhubekayo komaleko womda we-thermal kwandisa ngokubonakalayo utshintshiselwano lobushushu lwasekuhlaleni, ngelixa ulungelelwaniso lwe-spiral lwandisa indlela yolwelo, ivumela iqondo lobushushu{0}}umahluko wamandla okuqhuba ukuba usetyenziswe ngokupheleleyo kwaye ngokwenza njalo uphucula ukuhanjiswa kobushushu ngokubanzi.
III. I-Flow Intensification Mechanism
Ulwakhiwo lwe-helical luguqula ipateni ye-axial flow unidirectional efunyenwe kwimibhobho ethe ngqo yesiqhelo, ibeka ngaphezulu intshukumo ejikelezayo enqamlezayo kwi-axial flow kwaye ngokwenza oko idale indawo entsonkothileyo,{0}}enxamnye nemitha yedimensional flow.
·Oku kuhamba kwesibini kwandisa ukuxubana kolwelo, kukhuthaza ukuthambeka okufanayo kobushushu phakathi kolwelo olushushu nolubandayo, kwaye kuphucule ukusetyenziswa kwendawo esebenzayo yokufudumeza ubushushu.
·Nokuba kumanani aphantsi eReynolds, ijiyometri idala uqhushululu{0}}njengeziphumo zokuqina, iyenze ifaneleke ngakumbi{1}}kulwelo lwe-viscosity ephezulu okanye ii-transitional flow regimes.
·Ngaphezu koko, umqukuqelo onesiphithiphithi kakhulu unciphisa ukubakho kokubekwa kunye nokonakala kwendawo, ngaloo ndlela kunyuswa{0}}uzinzo lokusebenza kwexesha elide.
IV. IiParameters eziphambili zoYilo lweZakhiwo
·I-coil diameter yiparameter engundoqo ephembelela ukusebenza kokudluliselwa kobushushu; Idayamitha encinci ikhokelela kwigophe eliphezulu kunye nokuhamba kwesibini esomeleleyo kodwa ikwanyusa kakhulu ukwehla koxinzelelo, ifuna uyilo olulungelelanisiweyo olulinganisa ukusebenza kakuhle kunye nokusetyenziswa kwamandla.
I-coil pitch imisela ukubumbana kwendlela yokuhamba kwamanzi; inowuthi encinci yandisa ityhubhu{0}}icala lokuhamba indlela ngobude beyunithi kwaye yonyusa ubushushu bendawo yobushushu, nangona iphakamisa ubunzima bokwenza kunye nokumelana nokuhamba.
Ngaba akukho nto iphosakeleyo ngawe, kodwa inokuba nemiphumo emibi? Maxime, repellat, eleifend iste, eges.
Iqokobhe -uyilo lolwakhiwo olukwicala libaluleke ngokulinganayo; ukuqinisekisa ukuhanjiswa kolwelo okufanayo kubalulekile ukunqanda{1}}ukujikeleza okufutshane, iindawo ezifileyo, okanye iindawo zesantya esisezantsi sasekuhlaleni, njengoko le miba inganciphisa ngokubonakalayo ukuhanjiswa kobushushu kukonke.
V. Umgaqo-siseko we-Synergistic Thermal kunye ne-Aerodynamic Design
·Kuyilo lwehelical-zokutshintshana kobushushu bekhoyili, unxulumano oludityanisiweyo phakathi kokusebenza kobushushu kunye nokumelana nokuqukuqela kufuneka kuqwalaselwe, njengoko ukomelezwa kokudluliselwa kobushushu kuhlala kukhatshwa kukuhla koxinzelelo olwandileyo.
·Inkqubo yoyilo ikholisa ukujolisa kwi-coefficient yokhutshelo lobushushu (U{0}}ixabiso) ngelixa unyanzelela uluhlu oluvumelekileyo lokuhla loxinzelelo ukuze kuphunyezwe ukusebenza kakuhle kwamandla kwenkqubo.
·Ngokuhlenga-hlengisa iiparameters ezifana ne-coil radius, i-pitch, i-tube diameter, kunye ne-flow velocity distribution, ulungelelwaniso olufanelekileyo lunokuphunyezwa kwiimeko ezahlukeneyo zokusebenza; umzekelo,{0}}ubushushu obuphezulu-iimeko zomahluko zikhetha uyilo olunesiphithiphithi esikhulu, ngelixa izixhobo eziphantsi{2}}zamandla{3}}zokusebenzisa zikhetha izakhiwo ezinoxinzelelo oluphantsi.
·Uyilo lobunjineli luhlala lusebenzisa izibalo ezicandelwanayo okanye ukulinganisa amanani ukwenza ucazululo lwasekhaya lwemimandla yokuhambahamba eyahluka-hlukeneyo, ngaloo ndlela kuphuculwa ukuchaneka koyilo.
VI. IiMeko eziSebenzayo zokuSebenza kunye neeNzuzo zobuNjineli
I-Spiral-izitshintshi zobushushu zetyhubhu zifaneleke ngokukodwa-ulwelo oluphezulu lwe-viscosity (ezifana ne-oyile, iireyini, kunye neesyrups) kunye nemidiya equlathe amasuntswana aqinileyo okanye ethanda ukonakala, njengoko ukuqukuqela okugqithisileyo kunciphisa umngcipheko wokubekwa.

Zisetyenziswa ngokubanzi kwiikhemikhali, i-petroleum, ukusetyenzwa kokutya, amayeza, kunye neenkqubo zokubuyisela amandla, okwenza ukuba zibe zilungele ngakumbi izibonelelo zemveliso eziqhubekayo.
Ukongeza, ubume babo obubambeneyo kunye nokuchasana okunamandla kuxinzelelo lwe-thermal kuqinisekisa ukuthembeka okuphezulu phantsi kweemeko ezibandakanya umahluko omkhulu wobushushu okanye ukuhamba ngebhayisikile ye-thermal.
