Improvement in calculating methods for end?wall boundary layers of blade rows can only come about by a greater understanding of the physics of the flow from which realistic models can be built of the terms that go into ...

The present thesis is an experimental study of some aspects of unsteady two dimensional boundary layers subject to adverse pressure gradient. An adverse pressure gradient usually leads to boundary layer separation or an ...

An Experimental Study of Sudden Expansion in Pipe Flow Flow through a sudden expansion, though the simplest and perhaps the earliest problem of fluid flow separation, still leaves much to be understood. The sudden expansion ...

Experiments are done using a smooth solid rigid homogeneous acrylic sphere rolling on an inclined plane which is submerged in water. The motivation for these experiments comes from a need to understand a class of solid-fluid ...

Modeling of propagating discontinuities (cracks) is a challenging problem in the field of computational mechanics. Numerical techniques such as Finite Difference Method (FDM), Boundary Element Method (BEM), and Finite ...

Silicon photonics is a promising platform for photonic devices and circuits, largely driven by advanced complementary metal-oxide-semiconductor (CMOS) processing technology. An extremely crucial component for a photonic ...

Hard ceramic films of micrometric thickness deposited on a soft metallic substrate have ushered in a new era in the fabrication of structural, tribological, microelectronic and optical components. The mechanical performance ...

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 ...

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 ...
