FEASIBILITY ANALYSIS OF STEAM VENTILATION IN SUPERCAVITATION DESIGN

open access: yes, 2015
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

open access: yes, 2023
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

open access: yes, 2020
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

open access: yes, 2020
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 ...

Numerical Study on the Characteristics of Natural Supercavitation by Planar Symmetric Cavitators With Streamlined Headforms

open access: yes, 2017
A novel supercavitation-based device named Rotational Supercavitating Evaporator (RSCE) was recently designed for desalination. In order to improve the blade shape of rotational cavitator in RSCE for performance optimization and then design three ...

Cavitation & Supercavitation : From a bluff to a stable streamlined projectile

open access: yes, 2019
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 ...
