Abstract
U radu su provedena istraţivanja o postupcima izračunavanja pada tlaka trenjem kod horizontalnog dvofaznog strujanja za sistem zrak - voda u cijevi malog promjera. Kod primijenjenih protoka kapljevite odnosno plinske faze, opaţeni su različiti pojavni oblici dvofaznog strujanja: čepoliko, valovito, mjehurasto i udarno strujanje, te različiti prijelazni oblici. Za procjenu pada tlaka trenjem kod horizontalnog dvofaznog strujanja primijenjen je postupak po Bakeru i Lockhart Martineliju. Usporedbom eksperimentalnih i izračunatih vrijednosti pada tlaka ispitana je primjenjivost pojedinih modela. Na temelju rezultata izvedeni su zaključci o primjenjivosti i ograničenjima pojedinih postupaka za izračunavanje pada tlaka kod horizontalnog dvofaznog strujanja, u zadanim uvjetima rada.
Abstract (english)
The research about methods for calculating pressure drop caused by friction in horizontal two - phase flow for air - water system in a small diameter tube was made. At applying flow of liquid and gas phases, respectively, different forms of two - phase flow were observed: plug, wavy, bubble and slug as well as various transitional forms. Bakers and Lockhart Martinelli procedures have been applied for estimating pressure drop of the two - phased flow. Applicability of the models was tested by comparing with values obtained experimentally. Based on these results, conclusions about usability and limitations of certain models for pressure calculations in horizontal two phase flow were made.
