1. Numerical Study of Laminar, Transitional and Turbulent Flow Past Rectangular Cylinders
Abstract : The subject of flow past slender bluff bodies is of relevance to technical problems associated with energy conservation, structural design and acoustic emissions. The present work is restricted to an important sub-class of slender bluff body flow --- the incompressible flow around a stationary cylinder having a rectangular cross section, the cylinder being exposed to a constant free stream velocity.

2. Linear and non-linear dynamics of non-autonomous flows
Abstract : Fluid flows subject to time-dependent external forces or boundary conditions are ubiquitous in biology and technical applications. Whether one considers birds flying by flapping their wings or the gust response of wind turbines, the flow is non-autonomous. READ MORE

3. Microfluidic Preparation and Transport of Long DNA using Pillar Arrays
Abstract : This thesis presents a set of microfluidic tools and experimental studies for preparing (> 20 kbp) for genetic analysisas well as the transport of high-concentration, long-DNA solutions in pillar arrays.Long-DNA sample preparation with conventional gel-based techniques is slow (tens of hours to days) and laborious.

4. An experimental study on streamwise streaks in transitional boundary layers
Abstract : The present experimental study focuses on two topics, a passive transition-delay method for different types of wave disturbances and the effect of free-stream turbulence characteristics on boundary layer transition over a at plate. In the investigations, hot-wire anemometry was employed and the experiments were performed in a well-controlled wind tunnel facility. READ MORE
