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 ... -
1Some studies on experimental viscosity of refrigerant vapors R12, R14, R22 and R114 and their mixtures at elevator temp. & pressure pt2
The present investigation has been undertaken using two oscillating?disc viscometers. The first viscometer is a modified version of an earlier model to suit refrigerant vapours at pressures up to five atmospheres and ambient ... -
3D end wall flow in a compressor cascade
Improvement in calculation methods for end-wall boundary layers of blade rows can only come about through a greater understanding of the physics of the flow in that region. Most of the integral methods take the integration ... -
3D-Printing of Lunar Soil Simulant by Direct-Extrusion method.
The extrusion-based additive manufacturing (EAM) technique is recently being widely employed for the 3D printing of complex-shaped components made of ceramic powder (containing irregular-shaped particles) when it is cast ... -
A Systems approach for utility assessment of Energy resources in rural Applications
The main objective of the thesis is to develop a systems approach to assess the utilities of alternative energy resources in the context of rural India. The methodology proposed includes those energy resources also which ... -
Acoustic Source Characterization Of The Exhaust And Intake Systems Of I.C. Engines
(2010-07-15)For an engine running at a constant speed, both exhaust and intake processes are periodic in nature. This inspires the muffler designer to go for the much easier and faster frequency domain modeling. But analogous to ... -
Activated carbon-nitrogen adsorption cryocoolers : characterization of sub-systems and experiments on a laboratory model
This thesis deals with the development of a laboratory model of an activated?charcoal杗itrogen cryocooler to cater to heat loads of the order of 1 W in the temperature range 80�0 K. Among other aspects, adsorption and thermal ... -
Adaptive Mesh Redistribution for Hyperbolic Conservation Laws
(2018-03-19)An adaptive mesh redistribution method for efficient and accurate simulation of multi dimensional hyperbolic conservation laws is developed. The algorithm consists of two coupled steps; evolution of the governing PDE ... -
Aerobreakup of a Polymeric Droplet
Aerobreakup of a liquid droplet refers to the process of breaking the droplet into smaller fragments by subjecting it to a sufficiently high-speed stream of gas (generally air). This process lies at the core of various ... -
Air-Assited Atomization Strategies For High Viscosity Fuels
(2016-02-25)Atomization of fuel is an important pre-requisite for efficient combustion in devices such as gas turbines, liquid propellant rocket engines, internal combustion engines and incinerators. The overall objective of the present ... -
ALE-based Monolithic Finite Element Strategies for Fluid Structure Interaction Problems
Fluid-structure interactions (FSI) represent a class of engineering problems which involve a two-way coupling between the solid motion and the fluid flow. The deformation of the solid caused by the fluid forces at the ... -
An Experimental Study On The Scale Effects In Cavitation Noise
Cavitation noise studies were made in a water tunnel with particular reference to scale effects. Travelling?bubble cavitation was artificially generated on four axisymmetric bodies of the Schiebe head?forms with varying ... -
Analysis and Design of Organic Rankine Cycle based Power Plants
Solving the world’s energy crisis, and mitigating anthropogenic climate change, requires efficiently harnessing non-polluting renewable energy. Organic Rankine cycle (ORC) can be useful in this regard. ORC is Rankine cycle ... -
Analysis And Design Of Spatial Manipulators : An Exact Algebraic Approach Using Dual Numbers And Symbolic Computation
(2008-11-03)This thesis presents a unified framework for the analysis of instantaneous kinematics and statics of spatial manipulators. The proposed formulation covers the entire range of kinematic behavior, with kinematic singularity ... -
