Bubbly shock propagation as a mechanism for sheet-to-cloud transition of partial cavities (2016, background): “Gopalan & Katz (2000) in their study on cavitation in a nozzle found that a re-entrant jet developed when the cavity closure was in the region of adverse pressure.”
Dynamics of attached turbulent cavitating flows (2001, background): “The leading edge of a sheet cavity typically exhibits a finger-like structure [13].”
Time resolved PIV and flow visualization of 3D sheet cavitation (2006, methodology): “The first problem was avoided by the use of fluorescent tracer particles in combination with an optical filter in front of the camera lens blocking all laser light (Gopalan and Katz 2000; Bachert 2003).”
Vortex flow and cavitation in diesel injector nozzles (2008, background): “Other studies on cavitation performed in venturi-type nozzles, for example see Gopalan, Katz & Knio (1999) and Gopalan & Katz (2000), have employed laser diagnostics to provide insight into the mechanism of bubble entrapment into vortical flow structures, but the complexity of the geometry of…”
Analysis of cavitating flow structure by experimental and numerical investigations (2007, background): “…up to the present time, only a few authors have investigated the internal structure of such cavitating flow, whether by experimental means (Stutz & Reboud 1997a,b, 2000; Gopalan & Katz 2000) or by numerical calculations (Reboud, Stutz & Coutier 1998; Coutier-Delgosha, Reboud & Delannoy 2003a).”
Instantaneous pressure and material acceleration measurements using a four-exposure PIV system (2006, methodology): “The pressure measurement technique is applied to a cavity shear flow in a small water tunnel, which is described in Gopalan and Katz (2000). Since the primary objective of this paper is to introduce a new technique, we do not focus on the physics of this flow. The reader can refer to Tang and Rockwe”
Interfacial dynamics‐based modelling of turbulent cavitating flows, Part‐1: Model development and steady‐state computations (2004, background): “This nding is in good agreement with the experimental results of Gopalan and Katz [14], who have also studied sheet cavitation in a nozzle but with a di erent geometry and ow conditions.”
An experimental investigation into supercavity closure mechanisms (2016, result): “According to a number of prior studies (Gopalan & Katz 2000; Callenaere et al. 2001; Kshatriya et al. 2007), a slender cavity generated from a small cavitator does not yield sufficient adverse pressure gradient to create a re-entrant jet and consequently, TV is favoured.”
Numerical analysis of unsteady cavitating turbulent flow and shedding horse-shoe vortex structure around a twisted hydrofoil (2013, background): “10 increases as seen from the side view as it moves downstream, which is also consistent with the experimental observations by Gopalan and Katz (2000).”
