In the present study, heat transfer structures were investigated for thermal bridges on both intermediate floor beamed wall block and balcony extension intermediate floor beamed wall. Temperature and heat flux contours were obtained for all models in the case of internal and external insulation cases with different insulation thicknesses (Si = 3 cm, 5 cm and 7 cm). Results showed that high heat transfer rates were obtained in the region of heat bridges for all building models. However the heat transfer rate did not decrease on the heat bridge region in the case of internal insulation. The most appropriate insulation model was the external insulation case and it was also obviously determined that heat transfer rate decreased with increments of insulation thickness., U ovom radu istražuje se prijenos topline u toplinskim mostovima postavljenim na podovima međukatova i na balkonskim istakama. Određene su temperature i gustoće toplinskih tokova za sve modele za slučajeve vanjske i unutrašnje izolacije, s različitim debljinama izolacije (Si = 3 cm, 5 cm i 7 cm). Rezultati istraživanja su pokazali vrlo visoke vrijednosti toplinskih tokova u području toplinskih mostova kod svih ugradbenih modela. Doduše nije došlo do opadanja toplinskog toka u toplinskim mostovima u slučaju postavljanja unutrašnje izolacije. Puno se prikladnijim pokazao model u slučaju postavljanja vanjske izolacije i jasno je određeno da dolazi u tom slučaju do smanjenja toplinskog toka s povećavanjem debljine izolacije.

In the present study, it is proposed to investigate ice formation of natural convection and variously located cylinder arrangements in a cooling storage rectangular tank with filled water. For this purpose a Fluent package program was used to solve a flow domain with unsteady state conditions. Ice formation shapes and temperature distributions were shown. Water temperature in the tank and surface temperature of cylinders were taken as 4 oC and -10 oC respectively. Staggered and inline cylinder geometries were investigated for temperature distribution, velocity vectors and ratio of Aice/Acylinder (ice area/cylinder cross sectional area) by changing transversal and longitudinal spacing., Cilj ovog rada je istraživanje formiranja ledenog sloja prirodnom konvekcijom pri raličitim rasporedima cilindara u rashladnom spremniku punjenim vodom. Za tu je svrhu korišten programski paket FLUENT za rješavanje domene strujanja pri nestacionarnim uvjetima. Pokazani su oblici formiranja ledenog sloja i temperaturne raspodjele. Temperatura vode u spremniku i površinska temperatura cilindara bile su 4, odnosno -10 oC. Za šahovski i linijski raspored cilindara istraživan je raspored temperature, vektori brzina i omjer Aice/Acylinder (površina leda/površina poprečnog presjeka cijevi) u uzdužnom i poprečnom smjeru
