In this thesis that is entirely analytical in nature, nonlinear wave propagation in various structural-acoustic waveguide geometries is studied. The waveguides considered include a circular cylindrical waveguide with a ...

Axially grooved aluminium-ammonia heat pipes are extensively used for the thermal control of satellites. Heat pipes efficiently transfer waste heat from the electronic packages, housed inside the satellite, to thermal ...

Shock wave unsteadiness is an important phenomenon in high-speed aerodynamics. This phenomenon is observed in many locations of high-speed vehicles, such as supersonic inlets, ramjet engines, transonic airfoils, high-speed ...

Heavy fuel oil (HFO) is extensively used in industrial burners and marine engines. HFO droplet combustion gives rise to carbon particulates generated by pyrolysis, which are called cenospheres. There is a current hypothesis ...

The present study concerns experimental and numerical investigation of the combustion of low-calorific value syngas in an optically accessible reverse flow combustion chamber. Several modes of operation are investigated ...

Ribbons exhibit fascinating buckling-dominated behavior under mechanical loading because of a unique combination of geometric dimensions. The recent interest in examining engineering applications of ribbon-like structures ...

Solving the world’s energy crisis, and mitigating anthropogenic climate change, requires efficiently harnessing non-polluting renewable energy. Organic Rankine cycle (ORC) can be useful in this regard. ORC is Rankine cycle ...

Heat pipes are extensively used in spacecraft thermal control and electronics cooling for transfer of heat from high heat flux zones to low heat flux zones. The major advantage of heat pipe is it can transfer high heat ...

Coupling of spray with the coherent structures of a highly turbulent flow has been a long-standing problem especially in the context of liquid fuel delivery systems in gas turbine combustors. The atomizer in a gas turbine ...

In recent years, the growing concern about pollution from fossil fuels has resulted in an increased effort for utilization of low-grade heat sources such as industrial waste heat, solar energy and other renewable sources. ...
