Postopek oblikovanja profila lopatice Kaplanove turbine za ublažitev pojava kavitacije pri velikih pretokih : doktorsko delo

Podnar, Andrej

Raziskan je bil vpliv spremembe oblike dveh profilov kot sestavnih gradnikov lopatic gonilnikov Kaplanove turbine na pojav kavitacije. Cilj je izboljšati kinematiko vodnega toka okoli lopatic ... Kaplanovega gonilnika in s tem zmanjšanje pojava kavitacije na gonilnih lopaticah. Pričakovana posledica zmanjšanja kavitacije je poleg daljše življenjske dobe gonilnika tudi povečanje izkoristka turbine. Obsežna analiza kavitacijskih struktur je bila izvedena na dveh profilih in dveh gonilnikih. Obsegala je meritve integralnih veličin, vizualizacijo topoloških struktur, časovnih vrst in dinamiko obtekajočih tokov. Na podlagi teh analiz pa je bil razvit tudi kavitacijski model za napoved nastanka kavitacije glede na glavne vhodne parametre toka. Rezultati potrjujejo pravilno spremembo oblike profila in posledično oblike gonilnih lopatic glede na zmanjšanje nastanka kavitacijskih struktur. Potrjeno je bilo zmanjšanje nastanka kavitacijskih struktur in povečanja hidrodinamskega izkoristka modelne turbine.
