Tokovno toplotne razmere v ukrivljenih kanalih : magistrsko deloDelić, MarjanDelo obravnava termohidravlične razmere laminarnega toka tekočine v ozkih kanalih, ki jih lahko uporabimo za hlajenje temperaturno preobremenjenih delov naprav. Za pravilno izvedbo hlajenja je ... potrebno poznati lokalne hitrostne in toplotne razmere v kanalih, zaradi zmanjšanja lokalnih termičnih preobremenitev. V nerazvitih tokovnih pogojih dosega toplotna prestopnost visoke vrednosti tudi pri laminarnem toku tekočin. Pozornost smo posvetili tudi vplivu udara vtočnega curka. Numerično dobljene rezultate smo primerjali z izkustvenimi obrazci za hitrostno in temperaturno nerazvite profile in z eksperimentalnimi rezultati, kjer so bili ti na razpolago. Na ravnem kanalu smo spremljali razmere pri različnih Reynoldsovih številih in temperaturnih robnih pogojih. Med seboj smo primerjali tri izvedbe ukrivljenega oljnega kanala za hlajenje valja dieselskega motorja. Prav tako smo raziskovali vpliv spreminjanja masnega pretoka na toplotno-tokovne razmere v ukrivljenem kanalu.Izvršili smo tudi vezano obravnavo termo-hidravličnih pogojev v trdnini in tekočini. Razmere v tekočini smo v vseh primerih računali z metodo končnih volumnov, razmere v trdnini pa smo računali z metodo robnih elementov.Type of material - master's thesisPublication and manufacture - Maribor : [M.
