Abstract
U ovom završnom radu prikazani su rezultati laboratorijske analize strujanja zraka oko određenog objekta, kvadra. Dobivene su vrijednosti odstupanja prikupljenih podataka putem PLC – a i direktno preko transmitera za Average Pitot i Hot Wire. U radu su istaknute i regresijske krivulje koje su dobivene na temelju razlike očitanja između PLC – a i transmitera te se mogu koristit ubuduće za različite normirane brzine vrtnje ventilatora kako bi se došlo do točnih podataka i preko PLC – a. Provedena su i mjerenja koja omogućuju analizu utjecaja zida na uniformnost strujanja zraka te mjerenja kojima se opisuje turbulentno područje iza kvadra. Također, u ovom završnom radu objašnjeni su pojmovi vezani za aerodinamičnost objekata, vrste i dijelovi zračnih tunela, senzorika koja se primjenjuje prilikom mjerenja te problemi koji se pojavljuju prilikom strujanja fluida oko određenog tijela.
Abstract (english)
This undergradute thesis presents the results of a laboratory analysis of airflow around a specific object, a cube. Deviation values were obtained from data collected via PLC and directly through the Average Pitot and Hot Wire transmitters. The work highlights regression curves derived from the differences between PLC and transmitter readings, which can be used in the future for various standardized fan rotation speeds to obtain accurate data through the PLC. Measurements were also conducted to analyze the influence of a wall on airflow uniformity and to describe the turbulent region behind the cube. Additionally, this undergraduate thesis explains concepts related to object aerodynamics, types and components of wind tunnels, the sensing technology used in measurements, and challenges arising during fluid flow around a particular body.
