Turbulence interacts with flames over a multitude of lengthscales and timescales. These interactions are nonlinear and are ubiquitous, for example, in propulsion engines operating in space, air, land, and sea. ...

Pit toilets satisfy the sanitation requirement in regions with no access to piped sewerage facilities. Black water discharged from pit toilets is a major source of groundwater pollution. The primary focus of the thesis is ...

Droplet microfluidics provides controlled generation of monodispersed droplets of the order of a few picoliters in multiphase microfluidic systems. These droplets are employed as micro-reactors to conduct chemical/biochemical ...

There have been growing interest in Rendezvous and Docking (RVD) missions for on-orbit refueling, on-orbit servicing, orbital debris removal, etc. A very important requirement in RVD missions is soft-docking at the terminal ...

It is now well known that the strength of the metallic materials depends on microstructural features such as dislocation density, grain size, and precipitates. The migration of lattice defects such as dislocations is a ...

The lower part of the iron-making blast furnace is very important for operational stability and productivity of it. It represents a multiphase flow, including a cohesive zone. In order to reduce the coke consumption and ...

An ‘environmentally-benign design’ is defined as that which causes little or no harm to the natural environment and may be achieved by reducing the environmental impact of the design solutions conceptualised, to be ...

A real-time autonomous trajectory generation methodology for aerospace vehicles using pseudo-spectral based global collocation methods is presented in this thesis. The proposed method is formulated in a manner whereby ...

A myriad of physical processes in engineering and other science branches is represented using differential equations with boundary conditions. Finding the exact solution for the differential equation is quite challenging ...

The finite element limit analysis (FELA), which utilizes the concept of finite elements and an optimization procedure, is a very powerful technique to find an accurate solution of different stability problems in geomechanics. ...
