Analysis and simulation of ice storage air-conditioning systems
Ice?storage air?conditioning is a form of distributed load management. The system makes ice during off?peak periods and uses it to cool the building during on?peak periods. In the present work, an ice?storage air?conditioning ... -
Monte Carlo simulation of self assembled monolayers
We model and simulate the Self?Assembled Monolayer (SAM) of thiols (with a general chemical formula CH?�(CH?)?朣朅u) on a gold surface with the (111) index exposed. This system has been studied extensively by both experiments ... -
Neuromorphic solution to the inverse kinematic, problem of serial manipulators
A serial manipulator is a chain of alternating 搄oints� (revolute or prismatic) and 搇inks,� with one end fixed and the free end having an end?effector attached. For a manipulator to perform any task, one of the main problems ... -
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 ... -
Numerical studies on laminar internals seperated flows
In order to understand the nature of steady laminar incompressible separated flows, numerical solutions have been constructed for plane two-dimensional internal flows over a wide range of Reynolds numbers. Three aspects ... -
Numerical study of radiative transfer processes in the atmosphere
Radiative transfer constitutes an important physical process in the atmosphere. A detailed knowledge of the radiative balance of the Earth and the processes pertaining to the transfer of solar and terrestrial radiation is ... -
Intraseasonal variations of the tropical convergence zones in a simple monsoon model
In this thesis we have simulated the salient features of intraseasonal variation of the Indian summer monsoon using a simple monsoon model and unravelled the mechanisms governing these features. The monsoon model is a ... -

Modelling the lifted minimum phenomenon in the atmospheric
The Ramdas Paradox, also known as the lifted minimum phenomenon, has been a longstanding micrometeorological puzzle. It concerns the vertical distribution of air temperature which, near the ground during nights, generally ... -
Solar spectral diffuse radiance for a specified atmosphere
In many applications such as the design and performance evaluation of solar energy devices, remote sensing studies, meteorological and climatological studies, it is necessary to know the values of solar radiation reaching ... -
The use of dual quaternions in rigid body motion interpolation and visualization
Dual quaternions are an excellent alternative tool to transformation matrices in the study of rigid body motion. They are known to represent the position and orientation of a rigid body in a concise and efficient manner, ... -
Interface capturing in multiphase flows using finite volume based level set method
An important class of problems involves a substance transforming from one phase to another with absorption or emission of energy. Such cases arise in many settings, of which melting, solidification, condensation, and ... -
Constrained least squares finite element formulation of two-dimensional elastodynamic problems
In the present work, a least?squares finite element formulation for two?dimensional elastodynamic problems is developed. This development is based on an earlier formulation reported by Pratap. The earlier formulation was ... -
Experimental study of endwall flow in a compressor cascade
Improvement in calculating methods for end?wall boundary layers of blade rows can only come about by a greater understanding of the physics of the flow from which realistic models can be built of the terms that go into ... -
Electronic signal processing in laser doppler annemometry
The three commonly used electronic processors for laser Doppler anemometer systems are the spectrum analyser, the frequency tracking demodulator and the period timing device. Extensive analytical studies on spectrum analyser ... -
Boundary layer transition with and without lateral divergence
Information on the transition processes in turbomachine boundary layers is important in computing schemes for predicting blockage, flow losses, separation, etc. Actual transition on turbomachine blades does not conform to ... -
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 ... -
Rational approach to solid finite elements
The finite element method today has become a powerful tool in engineering analysis and design. The ease of application, reliability of solutions, and its ability to model complex geometries seem to be the main reasons for ... -
Studies on viscosity of mixtures of some freon vapours
An oscillating disc viscometer is used for the determination of viscosity of Freon?12, Freon?22 and Freon?114 vapours and their binary and ternary mixtures at room temperature and pressure. The viscosity of Freon?12, ... -
Studies on viscosity of mixtures of freon-12 and freon 22 vapours
The viscosity of pure Freon?12 and Freon?22 vapours, and their mixtures, has been determined using an oscillating?disc viscometer at room temperature and pressure. The results agree well with the published data for the ...
