A Study of Mode Dependent Energy Dissipation in 2D MEMS Resonators
(2018-02-25)With the advent of micro and nano electromechanical systems (MEMS/NEMS), there has been rapid development in the design and fabrication of sensitive resonant sensors. Sensitivity of such devices depends on the resonant ... -
Study Of Multiple Asperity Sliding Contacts
(2016-06-18)Surfaces are rough, unless special care is taken to make them atomically smooth. Roughness exists at all scales, and any surface-producing operation affects the roughness in certain degrees, specific to the production ... -
Study Of Solidification And Microstructure Produced By Cooling Slope Method
(2016-05-05)In most casting applications, dendritic microstructure morphology is not desired because it leads to poor mechanical properties. Forced convection causing sufficient shearing in the mushy zone of the partially solidified ... -
Study Of Squeeze Film Effects In Modelling Dynamic MEMS Devices
(2011-02-21)We present studies on squeeze film effects in dynamic MEMS devices with a special emphasis on the development of compact analytical models. First, the efficacy of lumped parameter modelling of dynamic MEMS devices is ... -
Study Of Stall Flutter Of An Isolated Blade In A Low Reynolds Number Incompressible Flow
(2015-07-08)Highly-loaded turbomachine blades can stall under off-design conditions. In this regime, the flow can separate close to the leading edge of the blade in a periodic manner that can lead to blade vibrations, commonly referred ... -
Study Of The Effect Of Elasticity Of The Added Mass In Mass Sensing Using Resonant Peak Shift Technique
(2013-05-21)Micromachined biosensors are used in chemical and biological applications. A biosensor which uses mass based transduction is called a mass sensor. Mass sensors are used to detect extremely small mass of biomolecules such ... -
A Study of Two Problems in Nonlinear Dynamics Using the Method of Multiple Scales
(2018-08-13)This thesis deals with the study of two problems in the area of nonlinear dynamics using the method of multiple scales. Accordingly, it consists of two parts. In the first part of the thesis, we explore the asymptotic ... -
Sub-Newtonian Coalescence in Polymeric Fluids
Droplet coalescence is a thermodynamic equilibration process driven by surface energy minimization. The physics of this phenomenon is characterized by the temporal evolution of a liquid bridge formed upon the proximate ... -
Supercritical CO2 Power Cycles and Turbomachinery Development for Renewable Energy and Waste Heat Recovery
Supercritical carbon dioxide (sCO2) power cycles have transitioned from the kilowatt level pilot facilities to the megawatt level demonstration plants. Theoretical studies and commercial benefits associated with sCO2, such ... -
Systematic Synthesis And Analysis Of Multi-DOF Toggle Mechanisms For Electrical Switches
(2015-12-07)Electrical switches are ubiquitous. Performance requirement for a switch is stringent. The operating mechanism mostly decides the performance of an electromechanical switch. However, design of such mechanisms, which involve ... -
Techno-Economic Evaluation of Rooftop Photovoltaic Systems in the Indian Context
Problems of greenhouse effect and depletion of conventional resources in the last two decades have resulted in a worldwide exponentially growing photovoltaic market for renewable power generation. The Indian government has ... -
Theoretical And Experimental Studies Of Capillary Pumped Loop And Loop Heat Pipe
(2010-07-13)Capillary pumped loop (CPL) and loop heat pipe (LHP), are two-phase heat transport devices which rely on surface tension induced by a fine pore wick to drive a working fluid in a loop. These are based on a working principle ... -
Thermal Performance of Various Roof Elements Under Different Weather Conditions
(2018-05-14)Beside the point of whether the country is developed or underdeveloped, energy crisis is a common scene all over the world. In order to balance energy supply and demand, either one has to increase the supply or decrease ... -
Thermal Turbomachinery Design for Closed Thermal Cycles and Multiple Fluids
Closed-cycle gas turbines can complement conventional power conversion systems due to their potential for improved efficiencies, compact system layouts, and the ability to exploit non-fossil fuel energy sources which leads ... -
Thermodynamic Analysis And Simulation Of A Solar Thermal Power System
(2014-05-21)Solar energy is a virtually inexhaustible energy resource, and thus, has great potential in helping meet many of our future energy requirements. Current technology used for solar energy conversion, however, is not cost ... -
Thermodynamics of Distributed Solar Thermal Power Systems with Storage
