Analiza termodinamičnega stanja plina v vodno-hidravličnem batnem akumulatorju pri dovajanju toplote med ekspanzijo plina

Kočevar, Uroš (author), Bombač, Andrej (mentor), Majdič, Franc (comentor)

Delo temelji na meritvah temperature in tlaka v vodnohidravličnem akumulatorju brez segrevanja in s segrevanjem plina med ekspanzijo dušika z dvema različno dolgima termočlenoma. Rezultati so v delu medsebojno primerjani in analizirani ter tudi primerjani z numeričnim izračunom opravljenim s programskim paketom Ansys Fluent. Pri numeričnem izračunu je bil dušik definiran kot idealni plin.

• Title: Analysis of the thermodynamic state of gas in a water-hydraulic piston accumulator with heating of gas during expansion of the gas

Abstract

Work is based on temperature and pressure measurements inside Piston-type Hydraulic accumulator with or without heating of nitrogen during expansion using two different lengths of thermocouples. Result are mutually analysed and compared and also compared with numerical calculation done in Ansys Fluent software. During the numerical calculation nitrogen was defined as ideal gas.
