Analytical Investigations on Linear And Nonlinear Wave Propagation in Structural-acoustic Waveguides
(2017-09-26)
This thesis has two parts: In the first part, we study the dispersion characteristics of structural-acoustic waveguides by obtaining closed-form solutions for the coupled wave numbers. Two representative systems are ...
Development And Investigation of Two-Stage Silica Gel + Water Adsorption Cooling Cum Desalination System
(2017-09-20)
The present research work caters to two important needs of rural India: i) desalination of subsoil/coastal brackish water and ii) basic refrigeration for short term preservations of agro-produce, medicines etc. Fortunately, ...
Studies On Fuel-Air Stratification And Combustion Modelling In A CNG-Fuelled Engine
(2016-11-19)
In-cylinder fuel-air mixing in a compressed natural gas (CNG)-fuelled, single-cylinder, spark-ignited engine is analysed using a transient three-dimensional computational fluid dynamic model built and run using STAR-CD, a ...
Structure of the Tropical Easterly Jet in NCAR CAM-3.1 GCM
(2018-04-24)
This thesis examines the structure of the Tropical Easterly Jet (TEJ) in a General Circulation Model (GCM). The TEJ is observed only during the Indian summer monsoon period and is strongest during July and August. The jet ...
Dynamics of Droplets Under Support, Acoustic And/Or Ambient Flow Excitation
(2018-04-24)
The first step on the way to understanding the complicated dynamics of spray is to study the behavior of isolated droplets. In many industrial and natural processes such as turbulent combustion, agricultural sprays, spray ...
Mechanics and Mechanisams in Fretting Damage for Stainless Steel and Chromium Carbide Coatings
(2018-04-11)
Fretting is a serious concern in many industrial components, specifically, in nuclear industry for the safe and reliable operation of the component/system. Till date, a lot of efforts has already been made to understand ...
Pragmatic Design of Compliant Mechanisms using Selection Maps
(2018-04-02)
A pragmatic method for designing compliant mechanisms is developed in this thesis, by selecting among existing mechanisms one that may be modified as required. This method complements existing techniques by answering ...
Static Balancing of Rigid-Body Linkages and Compliant Mechanisms
(2018-03-07)
Static balance is the reduction or elimination of the actuating effort in quasi-static motion of a mechanical system by adding non-dissipative force interactions to the system. In recent years, there is increasing recognition ...
Design and Development of Capacitive Micromachined Ultrasonic Transducers
(2018-02-22)
This thesis presents the design and analysis for development of a Capacitive Micromachined Ultrasonic Transducer (CMUT), a novel sensor and actuator, aimed at replacing the conventional piezoelectric transducers for ...
Experimental Studies on Extremely Small Scale Vibrations of Micro-Scale Mechanical and Biological Structures
(2018-05-14)
Experimental vibration analysis of mechanical structures is a well established field.Plenty of literature exists on macro scale structures in the fields of civil, mechanical and aerospace engineering, but the study of ...
