20.500.12556/DKUM-26267 Numerična analiza termo hidravličnih razmer v avtomobilski meglenki Numerical analysis of thermo hydraulic conditions in car fog lamp V prispevku obravnavamo vezan prenos toplote v trdnini in tekočini znotraj avtomobilske meglenke s programom za ra¡cunalniško dinamiko tekočin CFX [1]. Modelirani so vsi trije osnovni mehanizmi prenosa toplote: difuzija, konvekcija in sevanje. Predstavili bomo dva pristopa k modeliranju sevanja. Prav tako primerjamo rezultate izračunane kot laminarni in turbulentni tok, ker ocenjeno Raylightovo število nakazuje prehodni režim. Rezultati se dobro ujemajo z meritvami. In the article a coupled heat transfer in the solid and fluid inside of a car fog lamp is presented using CFD software CFX [1]. All three basic principles of heat transfer are dealt with: conduction, convection and radiation. Two different approaches to radiation modeling are compared. Laminar and turbulent flow modeling are compared since computed Rayleight number indicates transitional flow regime. Results are in good agreement with the measurements. prenos toplote računalniška dinamika tekočin halogenske žarnice termične napetosti heat transfer computer fluid dynamics car fog lamp true true false Slovenski jezik Angleški jezik Neznano 2012-05-31 12:21:00 2012-05-31 12:21:03 2022-04-15 03:41:15 2024-01-03 03:23:52 2008 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 536.24 12631318 URN:SI:UM:DK:BE3AHGES http://www.drustvozamehaniko.si/zbornik/ZbornikKD2008.pdf 1 https://dk.um.si/Dokument.php?lang=slv&id=35230 Fakulteta za strojništvo 0 0 0
