Convection Fani uye convection mienzaniso

Kana ruoko kuunza rakaita Mabumba kana yemichindwe yakaiswa pamusoro inopisa mundiro, mumwe anogona kunzwa kwebasa inodziya mhepo Rwako. Zvimwechetezvo zvinogona kuonekwa kana oscillation bepa jira wakaiswa pamusoro pachena womoto. Both Migumisiro zvinotsanangurwa ne convection.

Chii?

Hwaro Chiitiko pakati convection iri kuwedzera nyaya zvikuru chando neVadzidzi inopisa zvavo. Mumamiriro ezvinhu akadaro, nefuma kuti neshungu anorasikirwa arambe achirema uye igova vakareruka kupfuura dzakapoteredza nzvimbo inotonhora. Most chaizvo ichi chinoshamisa maitiro unoenderana kufamba kupisa fluxes pamusoro kudziyisa mvura.

Molecular inofamba mu pakatarisana mirayiridzo pasi pokudzora kupisa - izvi ndizvo chaizvo chii chinoita convection. Radiation, conduction uye kuita saizvozvo muitiro, asi rondedzera zvikurukuru kuchinjwa nokupisa mune zvinhu zvakaoma.

Chinozikamwa mienzaniso convection - kufamba inodziya mhepo iri pakati pamwe kudziyisa namano nzvimbo apo nenharo Rwako vatamire pasirin'i uye mhepo kutonhora rinokundwa pamusoro paburiro. Ndokusaka kana muchidziisa vakasimudza mhepo mukamuri zvinooneka inodziya kupfuura yepazasi chikamu mumba.

Archimedes mutemo, uye chafariz kuwedzera muviri

Kuti tinzwisise kuti munhu wechisikigo convection, zvichiitika rwakakwana nokuongorora muenzaniso romutemo Archimedes uye Chiitiko kuwedzera kwemiviri pasi pokudzora chafariz mwaranzi. Saka, maererano nemutemo, kuwedzera kupisa kunowedzera runodiwa vhoriyamu emura. The nenharo mvura iri pasi mumidziyo nhema pamusoro, apo unyoro hukuru arambe achirema ukuwo, Uchibviswa pazasi. Kana kudziyisa kubva kumusoro uye zvishoma gobvu mvura icharamba panzvimbo, munyika iyi, zviri Chiitiko hazvizoitiki.

The kwaita pfungwa

Kokutanga rokuti "convection" akanga dzataurwa nokuda Chirungu musayendisiti William Prut shure muna 1834. Rinoshandiswa kutsanangura kwebasa chafariz guru iri huru, zvinofamba zvinwiwa.

The zvidzidzo pamusoro Chiitiko pakati convection yokutanga yokungotaura vakatanga chete muna 1916. Panguva kuedza kwayo Vakawana kuti kuchinja kubva diffusion kuti convection ari pasi-neshungu zvinwiwa kunoitika apo vamwe yakaoma tembiricha tsika. Gare gare kukosha ichi akagamuchira tsanangudzo 'nhamba Roel. " Zvakange saka zita mukukudza vaongorori dzinobatanidzwa kwayo pakudzidza. The experimental Migumisiro kubvumirwa kutsanangura kufamba kupisa nokuyerera pasi pokudzora kwomudzimu Archimedes simba.

convection mhando

Kune mhando inoverengeka mananara vanorondedzerwa nesu - dzinongoitika uye vanomanikidzwa convection. MUENZANISO kufamba inopisa uye kutonhora mhepo Rwako pakati kamuri akanakisisa inozivikanwa dzinongoitika convection kwacho. Achitaura kumanikidzwa, zvinokwanisika kuchengeta mvura pamwe anonyandura chipunu, pombi kana stirrer.

Convection hazvibviri panguva kudziyisa nezvishoma. mhosva All zvakakwana simba kukwezvana pamusoro oscillation ose particulates. Somugumisiro, mashoko kudziyisa mitumbi rakasimba marongerwo regai simuka convection, nemwaranzi. Thermal conductivity unotsiva mananara aya mumiviri dzakadaro uye hwezvekukurukurirana kuchinjwa chafariz simba.

Zvitsaurei mhando nemabasa anonzi rirambe richibvira convection. Process kunoitika apo tembiricha Kuchinja munguva mvura iyerere achishandisa pombi. Under dzinongoitika ezvinhu, kukosha convection kwakadaro pamwe dzinongoitika uye akamanikidza chinhu chaizvo vasingakoshi. Zvisinei, muna muchadenga michina rirambe richibvira convection, nemwaranzi uye chafariz conductivity pakati zvinhu zvinokosha chaizvo zvinhu. Kunyange simba convective anodudzira mu weightlessness kunotungamirira nezvinetso zvinenge zvimwe rwokugadzira matambudziko.

Convection muna Wepasi goko akaturikidzana

pezvakaitwa Convection zvakabatana chaizvo pamwe zvepanyama chimiro gaseous zvinhu zviri pakukora yacho goko. Munokuridzirwa pose anogona ive nzvimbo zvinosanganisira anoverengeka concentric akaturikidzana. Pakati ndiyo hombe inopisa chinoumba, ndiro yakakwirira arambe achirema slurry ine simbi, nickel nedzimwe simbi.

Akapoteredza akaturikidzana pakati paNyika chinoumba ndivo lithosphere uye Semi-mvura jasi. The chapamusoro yepasi ndiyo zvakananga goko. Lithosphere akaumba pamusoro yoga mahwendefa vari vakasununguka inofamba, kutamira pamwe pemvura nemvura nejasi. Panguva kudziyisa jasi migove gogonera siyana uye matombo, izvo zvakasiyana sezvamunoita uye zvakasiyana arambe achirema, paumbwe convective dzenzvimbo. Yakanga nokupesvedzera Rwako kwakadaro pane zvakasikwa Kushandurwa penyanza mubhedha uye kutsigira kufamba makondinendi.

Kusiyana kubva convection kupisa conduction

Under chafariz conductivity rinofanira kunzwisiswa mano mitumbi kuti kuchinjwa zvokunyama kupisa kubudikidza inofamba mabhomba uye samolecular yeimwe. Simbi kuita zvakaisvonaka kupisa conductors, sezvo mamorekuru dzavo vari hworugare kuonana nomumwe. Kusiyana neizvi, gaseous volatiles uye protrude murombo conductors nokupisa.

Sei convection? The Physics acho anobva kupisa kuchinjirwa nokuda vakasununguka kufamba vakawanda samolecular zvinhu. Uyewo chafariz conductivity ndiyo bedzi muna simba kuchinjirwa pakati constituent tudonhwe muviri. Zvisinei, mumwe mumwe muitiro hazvibviri pasina kuvapo particulate nyaya.

mienzaniso zvakavapo

The nyore chaizvo kunzwisisa nyore muenzaniso convection inogona basa pakupfuura akangofananawo firiji. Kuparadzirwa dzaserera refrigerant gasi kuburikidza senyere pamusoro refrigerating mupanda kunoderedza yokumusoro mhepo akaturikidzana kuti tembiricha. Saizvozvowo, wakati chikatsiviwa Kupisa aibuda, kutonhora kunyura, nokudaro kutonhora zvigadzirwa.

Zvayaiva necheseri eDare mufiriji mabasa ave nesefa Kufananidzira inosimudzira kushaya kuti mhepo inodziya zvakapararira munyika compressor chikwata panguva gasi compression. Kutonhora yekamuri uyewo yakavakirwa convective zvigadziriswe. Hazvina nokuda kwechikonzero ichi hazvina akakurudzira nokuvhiringidza seri mufiriji. Chete iyi, kutonhora anogona kutora nzvimbo pasina dambudziko.

Mimwe mienzaniso convection anogona kuonekwa nokucherechedza zvakasikwa chinoshamisa akadai mhepo kufamba. Nenharo yakaoma pamusoro makondinendi uye dzaserera pamusoro munzvimbo ine zvakawanda zvakakomba ezvinhu, mhepo Rwako dzinotanga kubvisa mumwe, iyo inotungamirira kufamba kwavo, uye kufamba unyoro uye simba.

On convection rakasungirwa mukana ichikwira shiri uye gliders. Zvishoma gobvu uye inodziya mhepo makore pamwe gogonera kudziyisa panguva penyika achitungamirira paumbwe vachikwira Rwako kuti hwezvekukurukurirana chirongwa nokuipisa noutsi hwemvura. Kuti kukunda kunonyanyisa daro pasina nesimba uye simba shiri vanoda kukwanisa kuwana Rwako izvi.

Mienzaniso yakanaka convection - paumbwe utsi ari Chimneys and kuputika craters. Kutamira kukwira utsi inobva dzakakwirira tembiricha ayo uye kuderedza arambe achirema achienzaniswa zvakatipoteredza. At kutonhora utsi zvishoma nezvishoma yogara rezasi mhepo. Chikonzero ichi, maindasitiri nyere, kuburikidza icho pane akabuda kuti zvinokuvadza mumhepo, achiita zvichiita dzakakwirira.

Vakawanda mienzaniso convection muna Nature uye Technology

Zvezvisarudzo nyore, mienzaniso nyore kunzwisisa kuti inogona kuchengetwa zvakasikwa, upenyu hwezuva nezuva uye ruzivo rwokugadzira zvinhu, zvinofanira pachena:

• kufamba mhepo runoyerera panguva nokushanda weimba radiators;
• paumbwe uye kufamba namakore;
• muitiro mhepo kufamba, monsoon uye mhepo;
• Pasi misha tectonic mahwendefa;
• Pezvakaitwa kuti anonamata vakasununguka gassing.

kubika

Kuwedzera, asi chinonakidza kuti convection chaitwa vemazuva imba midziyo yemagetsi, kunyanya yamavira. Gas convection cabinet kunoita kubika ndiro siyana panguva imwe chete riri vakaparadzana siyana panguva tembiricha dzakasiyana. Panguva iyoyowo zvachose kunze vasanganise vanofarira uye Rinofembedza.

muchidziisa mhepo mune zvetsika muovheni iri inobva chete burner, iyo inotungamira kuti gogonera kugovera kupisa. Nokuda kuti chinangwa kwebasa inopisa mhepo nokuyerera achishandisa akazvitsaurira dzinoshandisa dhishi ari convection muovheni vane manune, akabika kuburikidza nani. mano kwakadaro kuchaita vakuchidzire, nokudaro achidzikisa nguva inodiwa pakubika.

Sezvinotarisirwa, madzimai epamba avo kubika muchoto kakati pagore, imba mudziyo pamwe convection basa haagoni kunzi rwokugadzira zvinokosha. Zvisinei, kune vaya vasingagoni kurarama pasina culinary kuedza, zano yakadaro yaizova nyore chinokosha mukicheni.

Tinotarisira akurukurwa raibatsira kwamuri. All yakanakisisa!
