1-D And 3-D Analysis Of Multi-Port Muffler Configurations With Emphasis On Elliptical Cylindrical Chamber
(2013-08-28)
The flow-reversal elliptical cylindrical end chamber mufflers of short length are used often in the modern day automotive exhaust systems. The conventional 1-D axial plane wave theory is not able to predict their acoustical ...
A Numerical Study of Droplet Dynamics in Viscoelastic Flows
(2017-10-05)
The polymers are integral part of vast number of products used in day to day life due to their anomalous viscoelastic behaviour. The remarkable flow behaviour exhibited by the polymeric fluids including rod climbing, ...
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, ...
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 ...
Development Of An Activated Carbon+ HFC 134a Adsorption Refrigeration System
(2009-04-01)
The demands facing the refrigeration industry are minimal usage of conventional energy sources for compression and avoidance of ozone depleting substances. One of the approaches to combat these issues is the use of thermally ...
Optimal Synthesis of Adjustable Four-Link Planar and Spherical Crank-Rocker Type Mechanisms for Approximate Multi-Path Generation
(2018-04-02)
The well known synthesis problem of obtaining dimensions of a four-link mechanism such that a point on the coupler link traces a desired path has been extensively studied. There are two types of path generation–path specified ...
