20.500.12556/RUL-106523 Using a dynamic and constant mesh in numerical simulation of the free-rising bubble A two-phase bubbly flow is often found in the process industry. For the efficient operation of such devices, it is important to know the details of the flow. The paper presents a numerical simulation of the rising bubble in a stagnant liquid column. The interFOAM solver from the open source Computational Fluid Dynamics (CFD) toolbox OpenFOAM was used to obtain the necessary data. The constant and dynamic computational grids were used in the numerical simulation. The results of the calculation were compared with the measured values. As expected, by using the dynamic mesh, the bubble trajectory was closer to the experimental results due to the more detailed description of the gas-liquid interface. two-phase flow free-rising bubble CFD volume of fluid (VOF) constant mesh dynamic mesh dvofazni tok vzgonsko gibanje mehurčka računalniška dinamika tekočin dinamična računska mreža konstantna računska mreža true false true Angleški jezik Slovenski jezik Članek v reviji 2019-03-01 10:37:43 2019-03-01 10:37:45 2022-08-19 03:46:16 0000-00-00 00:00:00 2019 0 0 9 str. iss. 1, art. 38 Vol. 4 Feb. 2019 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 532:519.62(045) 2311-5521 10.3390/fluids4010038 16497435 RAZ_Rek_Zlatko_2019.pdf RAZ_Rek_Zlatko_2019.pdf 1 0FFB20FFEA9B7293A3C735BE6AF014BD c03d571bb817de3e2c873ba3241e42d52e258ff2410fc02d0fc3e7436fa19f33 219ac592-31ad-11ec-abdb-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=149880 https://www.mdpi.com/2311-5521/4/1/38 0 0389b434-31ad-11ec-abdb-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=149879 Fakulteta za strojništvo 0 0 0
