20.500.12556/RUL-125102 Thermal analysis of a concrete dam taking into account insolation, shading, water level and spillover This study presents a procedure for modeling the heat transfer process in a concrete dam, taking into account the time-varying boundary conditions on the upstream and downstream sides of the dam (i.e., the water level of the reservoir, spillover, insolation, and shading) which affect the temperature conditions of the dam. The large concrete arch-gravity Moste Dam (in North West Slovenia) was analyzed, where an automated system for the measurement of concrete and water temperatures, and for the monitoring of meteorological effects, was installed. Thermal analyses (1D and 2D) for non-linear and non-stationary heat conduction through solids were performed using a finite element method (FEM) based program, TeEx, which was complemented by two specially developed programs for determining the effects of convection and insolation, considering also the effect of shading. A 15-day period was analyzed, as well as a period of one year. It was found that the results of the performed analyses fitted in well with the experimentally determined concrete temperature measurements. The results showed that at the insolated side of the dam, the temperature gradient was largest in a very narrow area along the concrete surface, but the temperature did not stabilize shallower than at a depth of about 6 m. As part of the thermal analyses, uncertainty analyses of the results of the calculations were also performed. concrete dam heat transfer solar radiation shading convection thermal analysis finite element method temperature monitoring temperature field uncertainty betonski jez prenos toplote sončno sevanje senčenje konvekcija toplotna analiza metoda končnih elementov interakcija človek-stroj true false true Angleški jezik Slovenski jezik Članek v reviji 2021-03-04 15:06:37 2021-03-04 15:06:41 2022-09-05 03:49:32 0000-00-00 00:00:00 2021 0 0 19 str. iss. 2, art. 705 Vol. 11 2021 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 624.012:627.82:621.8.035 2076-3417 10.3390/app11020705 46998275 RAZ_Zvanut_Pavel_2021.pdf RAZ_Zvanut_Pavel_2021.pdf 1 49230DC5251950F9C9C2386F2D2AFED3 bf907d494bfadcbcf49a7c1fb5d9b0b7e2ecc2206e26831582da429ebcf3a6ba 4ef67e96-8d79-11ec-abdb-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=153739 https://www.mdpi.com/2076-3417/11/2/705 0 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=140765 Fakulteta za gradbeništvo in geodezijo 0 0 0
