• Experimental Study of Flow Past a Circular Cylinder with a Flexible Splitter Plate 

      Shukla, Sanjay Kumar (2018-01-04)
      A circular cylinder is a geometrically simple bluff body that occurs in various practical applications. As with any bluff body, it exhibits large drag forces and a strong fluctuating lift force, both related to the strong ...
    • Flow Over A Circular Cylinder With A Flexible Splitter Plate 

      Shukla, Sanjay Kumar (2010-07-08)
      Previous work on rigid splitter plates in the wake of a bluff body has shown that the primary vortex shedding can be suppressed for sufficiently long splitter plates. In the present work, we study the problem of a flexible ...
    • Force Measurements On Rigid And Flexible Oscillating Foils 

      Jimreeves, M (2013-10-04)
      In the present work, we experimentally study thrust generation from sinusoidally pitched rigid and flexible foils immersed in a uniform flow. The flexible foils are made by attaching a flexible flap of known flexural ...
    • High Reynolds Number Flow Over A Backward-Facing Step 

      Nadge, Pankaj M (2016-06-21)
      Flow separation and reattachment happens in many fluid mechanical situations occurring in engineering applications as well as in nature. The flow over a backward-facing step represents a geometrically simple flow situation ...
    • Interaction of Bubbles with Vortical Structures 

      Jha, Narsing Kumar (2017-09-23)
      Bubbly turbulent flows occur in a variety of industrial, naval and geophysical problems. In these flows, the bubbles in the flow interact with turbulence and/or vortical structures present in the continuous phase, resulting ...
    • Maintaining Underwater Cassie State for Sustained Drag Reduction in Channel Flow 

      Dilip, D (2018-02-21)
      Water droplets tend to bead up on rough or textured hydrophobic surfaces by trapping air on the crevices underneath resulting in “Cassie” state of wetting. When a textured hydrophobic surface is immersed in water, the ...
    • Micro-PIV Study Of Apparent Slip Of Water On Hydrophobic Surfaces 

      Asthana, Ashish (2010-07-01)
      The condition of no relative velocity of fluid past solid is termed as ‘no-slip boundary condition’. This condition is a general observation in fluid mechanics. However, several research groups have recently reported slip ...
    • Unsteady Two Dimensional Jet with Flexible Flaps at the Exit 

      Das, Prashant (2017-11-13)
      The present thesis involves the study of introducing passive exit flexibility in a two dimensional starting jet. This is relevant to various biological flows like propulsion of aquatic creatures (jellyfish, squid etc.) and ...
