20.500.12556/DKUM-94148 Teslina turbina, konstruiranje modela turbine, meritev obratovalnih parametrov turbine diplomsko delo Tesla turbine, construction of turbine model, measurement of operating parameters V diplomskem delu je bil proučevan potencial uporabe Tesline turbine pri pridobivanju energije iz obnovljivih virov. Teslina turbina deluje na osnovi viskoznega trenja vodnega toka ob površini rotirajočih diskov. Zaradi preproste konstrukcije in nizkih stroškov predstavlja zanimivo alternativo klasičnim turbinam, predvsem za manjše energetske sisteme. V okviru raziskave je bil cilj proučiti vpliv različnih konstrukcijskih in obratovalnih parametrov, kot so razmik med diski, natok kapljevine in število vrtljajev rotorja, na moč in izkoristek turbine. Za ta namen je bil zasnovan in izdelan laboratorijski model Tesline turbine, ki je bil preizkušen v laboratoriju LAHET na vodni progi. Meritve so bile izvedene pri različnih vrtljajih in različnih kotih natoka vode (0°, 10° in 15°). Ugotovljeno je bilo, da imata razmik med diski in kot natoka pomemben vpliv na učinkovitost in moč turbine. Najvišji izmerjeni izkoristek je bil dosežen pri večjih kotih natoka vode, kjer je bila optimalna delovna točka dosežena pri nižjem pretoku. v Z analizo rezultatov je bilo ugotovljeno, da se pretok skozi turbino zmanjšuje s povečevanjem vrtljajev, kar je bilo pripisano centrifugalnemu učinku rotorja. Zaznane so bile tudi negativne vrednosti moči in izkoristka v režimih, ko je turbina delovala kot porabnik, torej jo je poganjal elektromotor. Izmerjeni maksimalni izkoristek je znašal približno 15 %, kar je – glede na izvedbo meritev in uporabljeni model – skladno z obstoječo literaturo. Na osnovi ugotovitev je bilo zaključeno, da Teslina turbina predstavlja obetavno tehnologijo za manjše nizkotlačne energetske sisteme, vendar je za izboljšanje njenega izkoristka potrebna nadaljnja optimizacija konstrukcijskih parametrov in obratovalnih pogojev. In this diploma thesis, the potential use of the Tesla turbine for energy generation from renewable sources was investigated. The Tesla turbine operates on the principle of viscous friction of the fluid along the surfaces of rotating discs. Due to its simple construction and low cost, it represents an appealing alternative to conventional turbines, particularly for small-scale energy systems. The aim of the study was to examine the influence of various constructional and operational parameters—such as disc spacing, fluid inlet angle, and rotor speed—on the turbine’s power output and efficiency. For the purposes of the research, a laboratory-scale Tesla turbine model was designed and built, and subsequently tested in the LAHET laboratory using a water channel. Measurements were carried out at different rotational speeds and inlet angles (0°, 10°, vii and 15°). It was found that both the disc spacing and the inlet angle had a significant impact on the turbine’s efficiency and power output. The highest measured efficiency was achieved at larger inlet angles, where the optimal operating point was reached at lower flow rates. The analysis of the results showed that the flow rate through the turbine decreases with increasing rotor speed, which was attributed to the centrifugal effect of the rotor. Furthermore, negative values for power and efficiency were observed in regimes where the electric motor was driving the turbine instead of the reverse. The maximum measured efficiency was approximately 15%, which is consistent with values reported in the existing literature, given the measurement setup and model used. In conclusion, the Tesla turbine is considered a promising technology for small, low-pressure energy systems. However, further optimisation of its constructional parameters and operating conditions is required to improve efficiency.
