Nekotorye Voprosy Techeniya Zhidkosti V Kanale: Rezul'taty Eksperimental'nogo Issledovaniya Aleksandr Sudarchikov Russian edition

Issledovany nekotorye problemy termo-gidrodinamiki pri techenii zhidkogo teplonositelya v kanalakh v adiabatnykh i diabatnykh usloviyakh. Predstavleny rezul'taty eksperimental'nogo issledovaniya krizisa techeniya zhidkogo azota v dlinnom, adiabatnom kanale malogo diametra pri nevysokikh davleniyakh. Izmereny kriticheskie znacheniya davleniya i raskhoda teplonositelya. Ustanovlena kolichestvennaya svyaz' mezhdu nimi. Pokazano, v chastnosti, chto pri krizise techeniya v kanale, voznikayushchiy skachok uplotneniya "zapiraet" kanal, sokhranyaya na ego bol'shey dline prezhnie dokrizisnye znacheniya rezhimnykh parametrov. Issledovany usloviya vozniknoveniya kolebaniy v potoke pri techenii zhidkogo azota v obogrevaemom kanale v usloviyakh vynuzhdennoy konvektsii. Pokazano, chto voznikayushchie v kipyashchem v kanale potoke azota kolebaniya, vyzvannye protsessami v samom potoke zhidkosti, yavlyayutsya razvitiem fonovykh kolebaniy (shuma), sushchestvuyushchikh v zhidkosti pri ee techenii v kanale. Rekomenduetsya dlya spetsialistov, interesuyushchikhsya problemami termo-gidrodinamiki pri techenii zhidkikh teplonositeley v kanalakh.
