kaņepju betons WUFI ēku izolācija Mitruma un siltuma pārnese Fizika termiskais starojums

description

Darba mērķis ir analizēt termisko inerci un mitruma pārnesi reālos laika apstākļos ēkas ārējās izolācijas konstrukcijās, kas sastāv no pētāmā materiāla - kaņepju betona. Šim pētījumam tika izvēlēta viendimensionāla problēmas nostādne WUFI programmatūrā. WUFI aprēķina iegūtie dati tiek salīdzināti ar eksperimentāli iegūtiem datiem. Lai noteiktu mitruma un siltuma pārnesi iekštelpās, tiek izveidots divdimensionāls un trīsdimensionāls telpas modelis ANSYS CFX vidē, iekļaujot termisko starojumu un konvekciju. Ģeometrija tiek izveidota pēc Latvijas Universitātes Botāniskajā dārzā esošā reālā stenda izmēriem. Ar WUFI iegūtie rezultāti pietiekami labi atbilst eksperimentāli iegūtajiem datiem. Izveidotie WUFI un CFX skaitliskie, kā arī materiālu modeļi ir pielietojami nākamajiem nepieciešamajiem pētījumiem.
