SUMMARY:Cavitational Flows / the Geometry of a Supercavitation Bubble
DESCRIPTION:Lecturer:Lotan Ludar\n Faculty:Department of Mathematics\n Inst
 itute:Technion – Israel Institute of Technology\n Location:Meeting Hall 
 203\, 2nd floor\, Fine Rocket Propulsion Center\,  Aerospace Engineering\n
  Zoom: \n Abstract: \n Details: \n Cavitation\, i.e. the appearance of vap
 or cavities inside an initially homogeneous liquid medium\, occurs in diff
 erent situations commonly characterized by the pressure decrease below the
  vapor pressure of the liquid. The vapor structures are often unstable\, a
 nd when reaching a zone of increased pressure\, they may violently collaps
 e. Thus\, at a first glance\, cavitation appears as a harmful phenomenon t
 hat should be avoided. The Russians were the first to identify a positive 
 implication of cavitation\, called supercavitation\, and built a torpedo b
 ased on this technology. As the cavitation parameter decreases\, a small c
 avity attached to an underwater body will extend and grow longer and longe
 r\, enveloping the entire body. Its overall drag with the surrounding will
  decrease significantly. Understanding the geometry of a supercavitation b
 ubble is essential to the design of supercavitational underwater vehicles 
 and applications. In a series of experiments we have investigated the deve
 lopment and shape of supercavitation bubbles under various operating condi
 tions and different cavitators. Using a new theoretical approach we have e
 xamined the bubble shape and its stability for different geometries and di
 sturbances. The research brings new insight for the phenomena of supercavi
 tation bubbles.
