Abstract
Tijekom izrade ovoga rada parametrizirana je geometrija Venturijeve cijevi u svrhu njenog što točnijeg mjerenja protoka. Model je izrađen, umrežen i simuliran u programu OpenFOAM. Parametrizacija i optimizacija se vršila pomoću programa Python i Python modula Inspyred. U svrhu boljeg razumijevanja problema teoretski su obrađene osnove uređaja koji mjere tlak na principu razlike tlakova, optimizacijskog problema kao i osnove analize strujanja fluida. Izrađena su tri modela cijevi koja su parametrizirana u Pythonu. Najbolji model koji aproksimira geometriju jednom spline krivuljom je optimiziran. Dobivena geometrija zbog vremenskog obima procesa optimizacije ne daje željenu točnost. Prepoznati su ključni razlozi i dane su preporuke za poboljšanje točnosti mjerenja protoka.
Abstract (english)
In this thesis the geometry of a Venturi tube has been parameterized, in order for it to achieve a high measuring accuracy. The model has been made, meshed and analyzed in the computer program OpenFOAM. Parameterization and optimization process was done with the help of Python and its module Inspyred. I order to better understand the problem a basic theoretical overview has been given of the theory of pressure differential flow meters, a generic optimization problem, as well as fluid flow analysis. Three Venturi tube models were made that approach the parameterization differently, in Python. The single spline curve model was found to be the most efficient, and has been optimized. The geometry hereby generated does not provide the desired measuring accuracy due to the very time demanding nature of the optimization process. Pointers on how to improve the quality of the simulation were identified and given.
