| Publisher Description: Probleme resheniya uravneniya Nav'e - Stoksa posvyashcheny dve moi knigi "Kvazilineynye uravneniya v chastnykh proizvodnykh" i kniga "Reshenie uravneniya Nav'e - Stoksa". No eksperimental'nogo podtverzhdeniya pravil'nosti kompleksnogo resheniya v etikh knigakh net. V dannoy knige proizveden raschet laminarnogo i turbulentnogo techeniya neszhimaemoy zhidkosti v tsilindricheskoy trube s kruglym secheniem na osnove resheniya uravneniya Nav'e - Stoksa. Dannye sravnivalis' s eksperimental'nym techeniem v truboprovode s "pesochnoy sherokhovatost'yu". Raschetnye dannye sovpali s eksperimental'nymi, krome chislennykh znacheniy perekhodnoy zony ot laminarnogo rezhima k turbulentnomu. Ne smotrya na to, chto opisanie turbulentnogo rezhima kompleksnoe, perekhodnuyu zonu eto reshenie opisyvaet kachestvenno. Eto ob"yasnyaetsya tem, chto v etoy oblasti imeyutsya kratnye polozheniya ravnovesiya, kotorye privodyat k khaoticheskomu rezhimu. Proiskhodit pereskok ot odnogo polozheniya ravnovesiya k proizvol'noy tochke, a dalee priblizhenie k drugomu polozheniyu ravnovesiya. T.e. vychislennye po polozheniyam ravnovesiya chislennye znacheniya teoreticheskikh krivykh kachestvenno sovpadayut s eksperimentom. Dannyy podkhod mozhno ispol'zovat' dlya opisaniya dvizhenie tela v zhidkosti. |
