Probleme resheniya uravneniya Nav'e - Stoxa posvyashheny dve moi knigi "Kvazilinejnye uravneniya v chastnyh proizvodnyh" i kniga "Reshenie uravneniya Nav'e - Stoxa". No jexperimental'nogo podtverzhdeniya pravil'nosti komplexnogo resheniya v jetih knigah net. V dannoj knige proizveden raschet laminarnogo i turbulentnogo techeniya neszhimaemoj zhidkosti v cilindricheskoj trube s kruglym secheniem na osnove resheniya uravneniya Nav'e - Stoxa. Dannye sravnivalis' s jexperimental'nym techeniem v truboprovode s "pesochnoj sherohovatost'ju". Raschetnye dannye sovpali s jexperimental'nymi, krome chislennyh znachenij perehodnoj zony ot laminarnogo rezhima k turbulentnomu. Ne smotrya na to, chto opisanie turbulentnogo rezhima komplexnoe, perehodnuju zonu jeto reshenie opisyvaet kachestvenno.

Proishodit pereskok ot odnogo polozheniya ravnovesiya k proizvol'noj tochke, a dalee priblizhenie k drugomu polozheniju ravnovesiya. T.e. vychislennye po polozheniyam ravnovesiya chislennye znacheniya teoreticheskih krivyh kachestvenno sovpadajut s jexperimentom. Dannyj podhod mozhno ispol'zovat' dlya opisaniya dvizhenie tela v zhidkosti.
