A Design Concept of a Volumetric Solar Receiver for Supercritical CO2 Brayton Cycle
(2018-01-09)Recently, the supercritical carbon dioxide (s-CO2) Brayton cycle has been identified as a promising candidate for solar-thermal energy conversion due to its potentially high thermal efficiency (50%, for turbine inlet ... -
Design Of Two-Axis Displacement-Amplifying Compliant Mechanisms Using Topology Optimization
(2010-07-14)This thesis deals with the design of two-axis displacement-amplifying compliant mechanisms (DaCMs) using topology optimization. The two-axis compliant mechanisms considered here are XY positioners and two-axis inertial ... -
Design, Analysis, Simulation and Experimentation of a Flexible Spine Quadruped
Quadrupeds robots can move on uneven and rough terrain where mobile robots cannot venture. Al-though bipeds have more capabilities, they are inherently unstable and difficult to control. Most quadrupeds today are built ... -
Developement Of Aluminium Foam : An Experimental And Numerical Study
(2010-07-06)Metal foams are lightweight structures and have large use in many components acting as impact energy absorbers. They have exceptional mechanical, thermal and acoustic properties. The design or selection of foam for packaging ... -
Development and Characterization of Ordered Magnetic Nanocomposite
Magnetic nano-particles dispersed in a non-magnetic matrix is promising for storage technology. Additionally, such magnetic nano composite (MNC) materials have potential applications in the field of telecommunication, ... -
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, ... -
Development And Performance Evaluation Of An Indirect Evaporative Air Cooler
(2014-09-09)Evaporative cooling is an alternative and efficient method of cooling in dry climates. When a liquid evaporates into the surrounding gas, the energy required for the change of phase produces a cooling effect. The wet bulb ... -
Development of a Flexible Actuator and Motion Planning for Endoscopic Robots
Endoscopy is a procedure by which a long flexible device called the `endoscope' is inserted into a patient's gastro-intestinal(GI) tract primarily for diagnosis. An endoscope is typically equipped with a camera, ... -
Development Of A Single Cylinder SI Engine For 100% Biogas Operation
(Indian Institute of Science, 2007-05-21)This work concerns a systematic study of IC engine operation with 100% biogas as fuel (as opposed to the dual-fuel mode) with particular emphasis on operational issues and the quest for high efficiency strategies. As a ... -
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 ... -
Development Of Efficient Modeling Methodologies Of Adhesively Bonded Joints For Crash Simulations
(2009-03-12)In this thesis, a new modeling methodology applicable to adhesively bonded joints for crash simulations is presented. Using this approach, adhesive joints can be modeled without using minute solid elements thus reducing ... -
Development of Microstructure, Texture and Residual Stresses during Friction Stir Processing of Aluminium Alloys
Friction Stir Processing (FSP) is emerging as one of the most competent Severe Plastic Deformation (SPD) methods for producing bulk ultra-fine grained materials with improved properties. The significant advantage of FSP ... -
Development of PCM coupled heat pipe for space application
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 ... -

Direct Estimation of Acoustic Source Characteristics of the Internal Combustion Engine Exhaust System and Analysis of Complex Muffler Configurations
Reduction in noise radiated from the IC engines is needed to meet the ever increasingly stringent noise regulations. The unmuffled exhaust noise of an IC engine is the biggest contributor to the overall engine noise. ... -
Direct Numerical Simulation of Square Vortex Flows
Atmospheric and oceanic flows are often modeled as two-dimensional due to their large planar extents (∼ 1000 km) and small vertical extent (∼ 10 km). Most phenomena in these systems are governed by the theory of two-dimensional ...
