Simulacija toka v Slivniškem jezeru z dvodimenzionalnim matematičnim modelom : diplomska naloga

Došler, Miha (author), Četina, Matjaž (mentor)

V diplomski nalogi so z dvodimenzijskim matematičnim modelom PCFLOW2D, razvitim na Katedri za mehaniko tekočin na Fakulteti za gradbeništvo in geodezijo Univerze v Ljubljani, izračunane simulacije toka v Slivniškem jezeru za različne tokovne situacije. V uvodnem delu je poudarek na opisu značilnosti jezera, karakteristik pregrade in opisu objektov, ki omogočajo varno in nemoteno obratovanje zajezitve ter izrabo električne energije. Naloga se nadaljuje z opisom računalniškega programa PCFLOW2D, temeljnih enačb in metode reševanja. V zadnjem delu so zajeta izhodišča za modeliranje toka v Slivniškem jezeru, obravnavane tokovne situacije, začetni in robni pogoji, ter na koncu rezultati in ugotovitve.

• Title: Water flow simulations at Lake Slivnica with two-dimensional mathematical model : Graduation thesis

Abstract

In this bachelor thesis, we used the PCFLOW2D two-dimensional mathematical model, developed at the Chair of Fluid Mechanics of the Faculty of Civil and Geodetic Engineering of the University of Ljubljana, to run a series of water flow simulations at Lake Slivnica. In the introduction, we highlight the characteristics of the lake and the barrier, as well as describe the structures enabling the safe and smooth operation of the barrier and energy generation. In the following chapters, we focus on the PCFLOW2D computer program and present the model itself, including some core equations and problem solving methods. The final section covers the grounds for the Lake Slivnica flow modelling, the flow situations studied, the initial and boundary conditions, and, in conclusion, the results and findings.
