This work is concerned with the application of compact and higher order compact (HOC) finite difference schemes to complex heat and mass transfer problems on nonuniform grids, which have been used overwhelmingly for fluid ...
Microchannel-based devices are widely used in microelectronic devices, turbine blade cooling, microfluidics for drug delivery devices, etc. Therefore, microchannel-based devices require the use of materials with high ...
Rigid pipes are used in almost every walks of life, starting from industries to domestic household for the transportation of fluids. All these pipes are subjected to wear and tear after a period of time. Any such wear and ...
We built prototypes of scissor linkages where it was noticed that angled-plane scissor linkage has significantly smaller lateral sway when compared with parallel-plane scissor linkage. It was further noticed that this ...
The objective of the present work is to develop a radiopaque, porous, and patient-specific shape memory polymer (SMP) based embolizing agent for interventional radiology technique that overcomes the limitations of the ...
In this work model-based identification of misalignment in coupled rotors with integrated active magnetic bearings is studied. The stiffness of the coupling is modelled as the sum of static stiffness and time-varying ...
This work is concerned with developing compact finite difference schemes for simulating incompressible viscous flows governed by the Navier-Stokes (N-S) equations on non uniform grids without transformations. The main work ...
The work presented in the thesis emphasizes mainly on the simultaneous identification of unbalance and misalignment faults as well as AMB stiffness parameters in a magnetically levitated rigid and flexible rotor system ...
The aim of the work is to develop an identification algorithm to estimate various rotor faults present in a rotor bearing system. The methodology considered both external and internal damping where the external damping ...

The present study is attempted to utilize the geometric and inertial nonlinearities along with modal interactions for piezoelectric based energy harvesting by extracting energy from parametric and galloping instabilities. ...
Dual-fuel engines fumigated with gaseous hydrocarbon fuels such as natural gas or liquefied petroleum gas (LPG) face the challenges of low thermal efficiency and high emissions of carbon monoxide (CO) and unburnt hydrocarbon ...
The applicability of graphene oxide (GO) and graphene for separation and purification applications is investigated using non-equilibrium molecular dynamics (MD) simulations. The effect of internal structure of the layered ...
The demand for good welding technologies and better weld quality aspects are increasing day by day with the development of advanced materials. The study of frictional stir joining of steel has attracted the attention of ...
Ferrofluid is a stable colloidal suspension of iron oxide particles in a non-magnetic carrier fluid. Traditional usage of ferrofluid were limited to multistage rotary seals, exclusion seals, inertia dampers, loudspeakers, ...
Polypyrrole based active actuator exhibits unique combination of properties such as low actuation voltage, high strain and stress, large bending displacement, low weight and high flexibility, biocompatibility and ...
Traditional metallic internal fixation devices (IFDs) have many limitations. To overcome the limitations, bioabsorbable polymer PLA was melt mixed with lab synthesized nano Hydroxyapatite powders (nHAp) through twin screw ...
A surface tension gradient resulting from the inhomogeneities in temperature (thermo-capillarity) or concentration (solutocapillarity) on the free surface of a pure or binary liquid has the ability to induce motion in its ...
