This book comprises select proceedings of the International Conference on Emerging Trends in Mechanical Engineering (ICETME 2018). The book covers various topics of mechanical engineering like computational fluid dynamics, heat transfer, machine dynamics, tribology, and composite materials. In addition, relevant studies in the allied fields of manufacturing, industrial and production engineering are also covered. The applications of latest tools and techniques in the context of mechanical engineering problems are discussed in this book. The contents of this book will be useful for students, researchers as well as industry professionals.

Bio-diesel manufactured from vegetable oils, animal fats and used cooking oils is an alternative fuel for diesel engines. It offers many advantages such as renewable, energy efficient, nontoxic, sulfur free and bio-degradable, and also offers cleaner combustion and reduces global warming gas emissions. The present work reports on the preparation of bio-diesel (methyl esters) from selected edible and non edible oils and their performance and emission characteristics. The experiments are carried out in three stages on a Single cylinder kirlosker diesel engine which is commonly used in agricultural sector. In the first stage, tests are carried out by fuelling the diesel engine with tallow oil methyl ester (TME) and its diesel blends. In the second stage, experiments are conducted by fuelling the diesel engine with bio-diesel with LPG blends. The engine is properly modified to operate under dual fuel operation using LPG as the blend fuel along with Diesel and TME as ignition source. Bio-diesel blended with LPG shows low emissions when compared to other blends.

This book has been prepared keeping in mind the need of a data book that covers all the areas in thermal engineering curriculum, namely, thermodynamics, heat and mass transfer, refrigeration and air-conditioning and solar energy. The data books generally available in the market are specific to any one of the above subjects but not all. The availability of such book as this makes the task of academic sections much easier as the need to supply to the students separate data books each for steam properties/tables, refrigerant tables/charts, heat transfer correlations, solar constants, etc. in university examinations will be eliminated. The book presents properties of various materials, tables/charts, formulae and empirical relations concerned with thermal engineering curriculum. The subject matter has been developed and compiled logically and integrated around a coherent central theme. This book will cater to the needs of undergraduate and postgraduate students of Mechanical, Industrial and Production, Chemical, and Aeronautical Engineering disciplines and also practising engineers. Salient Features: Detailed chapters on Thermodynamics, Heat and Mass Transfer, Refrigeration and Air-conditioning, and Solar Energy. Illustrative figures, wherever required. S.I. units are consistently used throughout the book. Comprehensive presentation of contents in the beginning for quick reference.
