Development of a Flexible Actuator and Motion Planning for Endoscopic Robots
Endoscopy is a procedure by which a long
flexible device called the `endoscope' is inserted
into a patient's gastro-intestinal(GI) tract primarily for diagnosis. An endoscope is typically
equipped with a camera, ...
On Flow Physics of Spinning Samaras
A particular form of winged seed (samara) dispersal technique adopted by nature uses
autorotative (unpowered rotation of the wing generating thrust force against gravity)
descent; for eg. in Maple and Mahagony trees. ...
New Mechanical Methods to Join Sheets in Lap and Butt Configuration and Analytical Model to Predict and Improve Clinching Joint Strength
Mechanical joining of sheets has many advantages over other joining methods in terms of wide variety combination of similar, dissimilar and non-metallic material sheet joining.
In conventional SPR joining, the rivet and ...
Flow and Forces on Rigid and Flexible Plates in Unsteady Rotational Motion
The swimming motion of fishes have long fascinated scientists and engineers. Over
the past few decades, researchers have studied physical models mimicking the tail beat
of fishes in an effort to extract key physical ...
Characterization of a large scale hypersonic shock tunnel and investigation of the effect of roughness on a large cone boundary layer flow
High speed flight is ridden with engineering challenges, some of which have been studied
for decades with only minor improvements. Boundary layer transition to turbulence in
highMach number flow is one such topic, which, ...
Liquid Jet in Swirling Cross Flow
Liquid jets in cross flows (JICF) have been an important part of spray research in the last few decades owing to the wide spectrum of applications ranging from agricultural sprays to aircraft gas turbine engines. However, ...
Phononic bandgap engineering in cellular periodic structures and mechanical metamaterials
A methodology has been developed for the computation of phononic band structure of cellular periodic structures, structures with spatially repetitive patterns, using Frequency domain Spectral Finite Element Method along ...
Propulsive Performance of Pitching Foils Investigated with Viscous Vortex Particle Method
Unsteady flapping foil based thrusters have emerged as ideal candidates for enabling propulsion in bioinspired
and bio-mimetic devices such as autonomous underwater vehicles. To a large extent, this
emergence has been ...
Investigation of an Axisymmetric Spiked Body in a Hypersonic Shock Tunnel
The forefront research in the regime of hypersonic flow is intended to focus on improving the overall performance of the existing aerospace vehicles. A high-speed vehicle experiences a high level of aerodynamic heating and ...
