Abstract (lt)

Tiriamas šilumnešio, tekančio vamzdžiu, temperatūros pereinamasis procesas tam tikru pasirenkamu atstumu nuo šilumnešio temperatūros vienetinio šuolio taško. Sudarytas šilumnešio temperatūros elektrinis analoginis modelis. Modelis sukuriamas ir tiriamas elektroninių schemų imitatoriumi PSpice, įeinančiu į programų paketą OrCAD. Nustatyta, kad šilumnešio temperatūros pereinamasis kitimas, tiksliai jį vertinant, nėra pirmojo laipsnio inercinis kitimas. Pateikiamos teoriniais skaičiavimais gautos išraiškos šilumnešio fronto temperatūrai ir nusistovėjusiai šilumnešio temperatūrai apskaičiuoti bei modeliavimo rezultatus apibendrinanti išraiška, pagal kurią galima įvertinti šilumnešio temperatūros pereinamojo kitimo laiko pastoviąją.

Abstract (en)

Transient temperature process of the heat carrier flowing in a conduit is investigated at a certain selected distance from the heat carrier temperature unit jump point. An electro analogical model of heat carrier temperature is designed. The model is realized and analysed by electrical circuits simulator PSpice included in the software OrCAD. It was defined that the transient change of heat carrier temperature is not the first order lag process when assessing it precisely. Expressions achieved by theoretic calculations are presented to calculate heat carrier front temperature and steady fluid temperature. Expression summarizing modelling results according to which it is possible to estimate the time constant of transient process of heat carrier fluid temperature is presented too.
