Is\u0131 transferi m\u00fchendisli\u011finde, kaynama olay\u0131 \u00f6nemlidir ve \u00e7e\u015fitli mekanizmalar arac\u0131l\u0131\u011f\u0131yla ger\u00e7ekle\u015fir. Kaynama, s\u0131v\u0131 bir maddenin gaz faz\u0131na ge\u00e7i\u015fini tan\u0131mlar ve bu s\u00fcre\u00e7te farkl\u0131 t\u00fcrlerde \u0131s\u0131 transferi meydana gelir. \u0130\u015fte kaynama \u0131s\u0131 transferi mekanizmalar\u0131n\u0131n 9 t\u00fcr\u00fc:<\/p>\n
Bu tip kaynama, s\u0131v\u0131n\u0131n y\u00fczeyindeki k\u00fc\u00e7\u00fck kabarc\u0131klar\u0131n olu\u015fturdu\u011fu \u00e7ekirdeklenme merkezlerinde ba\u015flar. S\u0131v\u0131 yeterli miktarda \u0131s\u0131 alarak buhar kabarc\u0131klar\u0131na d\u00f6n\u00fc\u015f\u00fcr. Homojen ve heterojen n\u00fckleasyon olarak ikiye ayr\u0131l\u0131r. Homojen n\u00fckleasyon \u00e7ok nadirdir ve saf s\u0131v\u0131larda ger\u00e7ekle\u015fir. Heterojen n\u00fckleasyon ise s\u0131kl\u0131kla y\u00fczey kusurlar\u0131 veya yabanc\u0131 par\u00e7ac\u0131klar \u00fczerinde ger\u00e7ekle\u015fir.<\/p>\n Bu t\u00fcrde, kaynama i\u015flemi ger\u00e7ekle\u015firken s\u0131cak y\u00fczeyde gaz kabarc\u0131klar\u0131 olu\u015fur ve y\u00fckselir. Bu kabarc\u0131klar y\u00fckseldik\u00e7e, etraflar\u0131ndaki s\u0131v\u0131y\u0131 da hareketlendirir ve \u0131s\u0131 transferini art\u0131r\u0131r. Bu s\u00fcre\u00e7 kabarc\u0131klar\u0131n birle\u015fmesi ve y\u00fczeye ula\u015fmas\u0131 ile devam eder.<\/p>\n Serbest y\u00fczey kaynamas\u0131, s\u0131v\u0131n\u0131n a\u00e7\u0131k bir y\u00fczeyde kaynamas\u0131 durumudur. Bu tip kaynamada y\u00fczey buharla\u015fmas\u0131 artarak kabarc\u0131k olu\u015fumuna yol a\u00e7ar. Geleneksel bir tencerede su kaynatma \u00f6rne\u011fi bu t\u00fcr kaynamaya \u00f6rnektir.<\/p>\n Zorlanm\u0131\u015f y\u00fczey kaynamas\u0131, s\u0131v\u0131 bir y\u00fczey \u00fczerinde zorland\u0131r\u0131larak (\u00f6rne\u011fin, pompalanarak) kaynamad\u0131r.

Bu n\u00fckleat\u00f6rler, n\u00fckleasyon merkezlerini art\u0131rarak kaynama s\u00fcrecini iyile\u015ftirir.<\/p>\n Film kaynamas\u0131, y\u00fczeyde buharla\u015fma sonucunda olu\u015fan bir buhar filmi yoluyla \u0131s\u0131 transferi yap\u0131l\u0131r. Bu t\u00fcr kaynama, y\u00fcksek y\u00fczey s\u0131cakl\u0131klar\u0131nda g\u00f6r\u00fcl\u00fcr ve film tabakas\u0131 \u0131s\u0131 iletimini \u00f6nemli \u00f6l\u00e7\u00fcde etkiler.<\/p>\n K\u00fcrelik noktas\u0131, s\u0131v\u0131n\u0131n y\u00fczey s\u0131cakl\u0131\u011f\u0131 \u00e7ok y\u00fcksek oldu\u011funda g\u00f6r\u00fcl\u00fcr. Bu durumda, s\u0131v\u0131 damlalar\u0131 y\u00fczeyle temas etmek yerine buhar tabakas\u0131 \u00fczerinde “y\u00fczer”. Bu, buhar tabakas\u0131n\u0131n iletkenlik \u00f6zelliklerinden dolay\u0131 d\u00fc\u015f\u00fck \u0131s\u0131 transferine neden olur.<\/p>\n Ge\u00e7ici kaynama, y\u00fczeyde k\u0131sa s\u00fcreli h\u0131zl\u0131 s\u0131cakl\u0131k de\u011fi\u015fimleri ile kaynamad\u0131r. Bu t\u00fcr kaynama, genellikle ani \u0131s\u0131 giri\u015fleri veya di\u011fer d\u0131\u015fsal etkilerle g\u00f6zlemlenir.<\/p>\n Yanma kaynamas\u0131, yanma reaksiyonlar\u0131 s\u0131ras\u0131nda olu\u015fan \u0131s\u0131n\u0131n s\u0131v\u0131y\u0131 kaynama noktas\u0131na getirmesi durumudur.
