20.500.12556/RUL-133197 Optimization of a single tube practical acoustic thermometer When designing a single tube practical acoustic thermometer (PAT), certain considerations should be addressed for optimal performance. This paper is concerned with the main issues involved in building a reliable PAT. It has to be emphasised that a PAT measures the ratio of the time delay between the single temperature calibration point (ice point) and any other temperature. Here, we present different models of the speed of sound in tubes, including the effects of real gases and an error analysis of the most accurate model with a Monte Carlo simulation. Additionally, we introduce the problem of acoustic signal overlap and some possible solutions, one of which is acoustic signal cancellation, which aims to eliminate the unwanted parts of an acoustic signal, and another is to optimize the tube length for the parameters of the gas used and specific temperature range. acoustic waveguide thermometer temperature speed of sound real gas Monte Carlo simulations akustični valovod termometer temperatura hitrost zvoka neidealni plin simulacija Monte Carlo true false true Angleški jezik Slovenski jezik Članek v reviji 2021-11-17 08:07:02 2021-11-17 08:07:05 2022-09-12 04:15:17 0000-00-00 00:00:00 2020 0 0 19 str. iss. 5, art. 1529 Vol. 20 Mar. 2020 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 621.317:536.5 1424-8220 10.3390/s20051529 22292739 RAZ_Tavcar_Rok_2020.pdf RAZ_Tavcar_Rok_2020.pdf 1 711B29E8220C812471EBEE89739EF20C 21bdd54971a1cee3edcb26b03624c0601caac55179f67a319401e48037afa331 3b3ea7d7-4775-11ec-abdb-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=151077 https://www.mdpi.com/1424-8220/20/5/1529 1 e72bb408-4774-11ec-abdb-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=151076 Fakulteta za elektrotehniko 0 0 0
