Vpliv oblike difuzorja na delovne karakteristike radialnega kompresorja : doktorsko deloKmecl, TomažPri radialnih kompresorjih uvrščamo difuzorje v dve osnovni kategoriji: difuzorje z lopaticami in difuzorje brez lopatic. Difuzorji z lopaticami imajo ozko delovno območje, toda dober izkoristek. ... Temu nasprotni so difuzorji brez lopatic, ki imajo majhen izkoristek, vendar omogočajo stopnji široko delovno območje. Če hočemo doseči oboje, dovolj široko delovno območje in zadosti visok izkoristek stopnje, je potrebno uporabiti difuzor, ki združuje prednosti obeh tipov difuzorjev. V okviru te raziskovalne naloge smo ugotavljali vpliv posameznih geometrijskih parametrov rotorja in difuzorja na izkoristek in velikost delovnega območja stopnje. Pri tem smo podrobneje analizirali vplive dolžine difuzorske lopatice, števila difuzorskih lopatic, oddaljenosti rotorja in difuzorja, vstopnega kota difuzorske lopatice, profiliranosti difuzorskih lopatic, širina kanala difuzorja in vpliv Machovega števila. Kvalitativni in kvantitativni vpliv posameznega parametra smo določili s pomočjo meritev, numeričnih simulacij in statistične obdelave izmerjenih rezultatov. Rezultati raziskave kažejo, da posamezen geometrijski parameter nima odločilnega vpliva na karakteristike stopnje. Pokazalo se je, da je za dobre karakteristike stopnje bolj pomembna pravilna kombinacija omejenih geometrijskih parametrov, kot vsak parameter posebej (pa četudi je optimiran).Type of material - dissertation ; adult, seriousPublication and manufacture - Ljubljana : [T.
