FEASIBILITY ANALYSIS OF STEAM VENTILATION IN SUPERCAVITATION DESIGN
The complete envelopment of a submerged object by a continuous cavity, or supercavity, results in significant reduction of the skin drag acting on the object, allowing for substantial increases in the maximum speeds of underwater devices.

The dynamics of supercavitation and the possibility of incorporating cold plasma inside it
Izven obsega negativnih učinkov, mikavnost spreobrnitve kavitirajočih tokov v koristne procese še naprej sproža nešteto radovednih prizadevanj. Eno teh sloni na hipotezi, da je v dovolj velikem in stabilnem superkavitacijskem mehurju možno vzdrževati ...

SPATIO-TEMPORAL DEVELOPMENT OF SUPERCAVITATION OVER AN IMPULSIVELY LAUNCHED PROJECTILE
Supercavitation inception and formation was studied over blunt projectiles. The projectiles were fired using a gas gun method. In this method, projectiles are launched under the action of expanding detonation gases.

Experimental modelling of supercavitation on various venturi restriction geometries
V sklopu zaključne naloge smo opravili eksperimentalne meritve za potrebe razvoja merilnega testnega dela, kjer bo formiran superkavitacijski oblak. Različne geometrije smo zasnovali v modelirniku (SolidWorks), jih dali izdelati iz akrilnega stekla in ...

Cavitation & Supercavitation : From a bluff to a stable streamlined projectile
Supercavitation uses the phase transition liquid-gaseous, triggered by the fast motion of a projectile, to streamline its shape and reduce its drag. In this thesis, we address several aspects of supercavitation: cavitation triggered by acceleration in a ...

Stability of Oblique Water Entry of Cylindrical Projectiles
Water entry is an interesting subject but many of its physical aspects have remained unknown so far. Using computational fluid dynamics (CFD), this study investigates the dynamic stability of cylindrical projectiles in the oblique water entry at shallow ...
