In this book on Natural (or, Free) convection, many problems of practical interest are solved using Mathcad, Engineering Equation Solver (EES) and EXCEL.

As done in other books in this series, viz. “Software Solutions to Problems on Heat Transfer”, much emphasis is given on the use of these software to conduct parametric analysis and present graphical representation of results.

In ‘Natural or free convection’, fluid movement is caused because of density differences in the fluid due to temperature differences, under the influence of gravity. Obviously, as compared to Forced convection, the heat transfer coefficient is lower in the case of Natural convection.

Still, Natural convection is one of the important modes of heat transfer used in practice since there are no moving parts and as a result, there is an increased reliability.

We shall solve problems of Natural convection involving following geometries: Vertical plates and cylinders, horizontal plates, cylinders and spheres, different types of enclosed spaces, rotating cylinders, disks and spheres. We will also consider important problems of Natural convection from finned surfaces, and cases of combined Natural and Forced convection.

This book is very good for all UG, PG and Ph. D. students. The solutions for the various problems are excellent. The Mathcad software is used very efficiently and intelligently for solving the problems.. I am using this book for my research work sponsored by ASHRAE.

Dr. M. Thirumaleshwar

Dr. M. Thirumaleshwar graduated in Mechanical Engineering from Karnataka Regional Engineering College, Surathkal, Karnataka, India, in the year 1965. He obtained M.Sc (cryogenis) from University of Southampton, U.K. and Ph.D. (cryogenics) from Indian Institute of Science, Bangalore, India.

He is a Fellow of Institution of Engineers (India), Life Member, Indian Society for Technical Education, and a Foundation Fellow of Indian Cryogenics Council.

He has worked in India and abroad on large projects in the areas involving heat transfer, fluid flow, vacuum system design, cryo-pumping etc.

He worked as Head of Cryogenics Dept. in Bhabha Atomic Research Centre (BARC), Bombay and Centre for Advanced Technology (CAT), Indore, from 1966 to 1992.

He worked as Guest Collaborator with Superconducting Super Collider Laboratory of Universities Research Association, in Dallas, USA from 1990 to 1993.

He also worked at the Institute of Cryogenics, Southampton, U.K. as a Visiting Research Fellow from 1993 to 1994.

He was Head of the Dept. of Mechanical Engineering, Fr. Conceicao Rodrigues Institute of Technology, Vashi, Navi Mumbai, India for eight years.

He also worked as Head of Dept. of Mechanical Engineering and Civil Engineering, and then as Principal, Vivekananda College of Engineering and Technology, Puttur (D.K.), India.

He was Professor and coordinator of Post-graduate program in the Dept. of Mechanical Engineering in St. Joseph Engineering College, Vamanjoor, Mangalore, India.

A book entitled “Fundamentals of Heat and Mass Transfer” authored by him and published by M/s Pearson Education, India (2006) has been adopted as a Text book for third year engineering students by the Visweswaraya Technological University (V.T.U.), Belgaum, India.

He has authored a free e-book entitled “Software Solutions to Problems on Heat Transfer” wherein problems are solved using 4 software viz. Mathcad, EES, FEHT and EXCEL. This book, containing about 2750 pages, is presented in 9 parts and all the 9 parts can be downloaded for free from www.bookboon.com.

He has also authored free e-books on Thermodynamics entitled “Basic Thermodynamics: Software Solutions” and “Applied Thermodynamics: Software Solutions” wherein problems are solved using 3 software viz. Mathcad, EES, and TEST. Each of these titles is presented in 5 parts and all the books can be downloaded for free from www.bookboon.com.

He has also written and published three booklets entitled as follows:

1. Towards Excellence…How to Study (A Guide book to Students)
2. Towards Excellence…How to teach (A guide book to Teachers)
3. Towards Excellence…Seminars, GD’s and Personal Interviews (A guide book to Professional and Management students)

Dr. M. Thirumaleshwar has attended several National and International conferences and has more than 50 publications to his credit.
