20.500.12556/DKUM-66735 Determining the speed of sound, density and bulk modulus of rapeseed oil, biodiesel and diesel fuel Modern tendencies in the development of diesel engines include the operation of the system for injecting diesel fuel at pressures higher than 100 MPa. Knowing the characteristics of liquid fuels such as speed of sound, bulk modulus and density depending on pressure, is important for predicting the behavior of fuel injection systems for diesel engines and optimization of the same. The paper presents an original method and apparatus (device) for determining the speed of sound and density of fluids depending on the pressures. With this method, values of these characteristics for rapeseed oil, biodiesel and conventional diesel fuel at pressures up to 160 MPa are determined. The method is non-destructive, it can also be applied to higher pressures than 160 MPa, as well as other liquid fluids that are used at high pressure - hydraulic oil, for example. biodiesel rapeseed oil speed of sound bulk modulus density high pressure biodizel biodiesel repično olje hitrost zvoka stisljivostni modul gostota visok tlak true false true Angleški jezik Slovenski jezik Znanstveno delo 2017-07-07 09:44:27 2017-07-07 09:45:17 2022-08-01 13:06:39 2019-07-11 15:57:12 2012 0 0 str. 505-514 suplement 2 Letn. 16 2012 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 0354-9836 621.43.013.43 43417089 16751382 10.2298/TSCI120426187N 0354-9836 URN:SI:UM:DK:JOMWT0CL Thermal_Science_2012_Nikolic_et_al._Determining_the_speed_of_sound,_density_and_bulk_modulus_of_rapeseed_oil,_biodiesel_and_diesel_fuel.pdf Thermal_Science_2012_Nikolic_et_al._Determining_the_speed_of_sound,_density_and_bulk_modulus_of_rapeseed_oil,_biodiesel_and_diesel_fuel.pdf 1 00086899D6E76323E8AD29D989BED84B 2dddbad58719293da7f6c9b76cedc50dfd65607fd053930b7c5bb914ceaeb12c 600b1d17-7c0e-11eb-bb7a-00155d0001ca 20.500.12556/dkum/22823d28-cf01-4848-8693-cf4dcf2be331 https://dk.um.si/Dokument.php?lang=slv&id=113834 http://www.doiserbia.nb.rs/Article.aspx?ID=0354-98361200187N 1 https://dk.um.si/Dokument.php?lang=slv&id=113833 Fakulteta za strojništvo 0 0 0
