Hierarchical Composite Materials: Materials, Manufacturing, Engineering/ Kaushik Kumar, J. Paulo Davim.
No full textIn English.Includes bibliographical references and index.Hierarchical Composite Materials provides an in-depth analysis of a class of advanced composites that have properties that are anisotropic due to structural organization at different length scales. Chapters address how ordering occurs from the atomic-scale up to the microstructure and how control of these factors leads to the final materials' properties. Manufacturing procedures, properties, and applications of different functionally graded materials are discussed in detail. This book is ideal for materials scientists, mechanical engineers, chemists and physicists.Zindani, Divya / Kumar, Kaushik / Davim, J.

A Parametric Study of Functionally Graded Rotating Annular Fin
No full textAbstractPerformance analysis of the rectangular annular fins made of functionally graded material subjected to rotation is reported in the present work. The governing differential equation for the fins has been derived to study the temperature distribution of the fins with insulated tip. A parametric study is then carried out by varying grading parameters along with the parameter of dimensionless rotational speed of the shaft in the governing equation to investigate the effect of on fin performance. The results are presented in graphical form. The formulation is validated with benchmark results and good agreement is observed
A Simulation Based Study of Flow Velocities across Cross Flow Turbine at Different Nozzle Openings
No full textAbstractThe present work reports CFD based investigation of the effect of design parameters on the flow velocities of a cross flow turbine (CFT). Best described as an impulse type turbine with partial admission of air, cross flow turbines meet the demand for an efficient turbine to run at low head that is also easy to manufacture. The design of cross–flow turbine is unique due to the generation of power during two stages. This type of turbine is often used in small hydropower plants located in less–developed countries. The design parameters of CFT that can be varied to increase overall efficiency and power output of the turbine are water inlet angle, blade angle at inlet and outlet. In the present work the design parameters are varied for different nozzle openings and simulated using CFD. A full 3-D steady state flow simulation of the cross-flow turbine is performed including casing, runner and nozzle assembly
Thermodynamic analysis of diesel engine using producer gas as secondary fuel
No full textPaper presented to the 10th International Conference on Heat Transfer, Fluid Mechanics and Thermodynamics, Florida, 14-16 July 2014.The proposed work reports a combustion model for a dual fuel
CI engine for Diesel cycle and Dual cycle. The work then
analytically examines the performance of a CI engine with the
minimum use of diesel as primary fuel, with producer gas as
secondary fuel. The performance has been analysed for work
output and thermal efficiency. The combustion model has been
developed for ideal diesel engine, diesel-producer gas engine
with diesel as primary fuel. The combustion models have been
simulated using MATLAB® codes. The specifications of a
standard CI engine have been used for numerical calculations.
The equation of state in each process in the cycles has been
critically analysed based on laws of thermodynamics. The
performance analysis shows that, in a diesel-producer gas
engine, thermal efficiency increases and work done decreases
as the percentage of diesel supplied during combustion process
decreases. Also, the addition of producer gas in a dual-fuel
(Diesel-Producer gas) engine allows the engine to run over a
lower range of maximum temperature of the cycle which
reduces the chances of Nox formation.dc201
