This book, viz. Cryogenic Engineering: Software solutions – Vol II, is the second in the series on Cryogenic Engineering: Software Solutions, and deals with the liquefaction of gases.

Vol I of the series, published earlier, dealt with: Introduction and properties of cryogenic fluids and properties of materials at low temperatures. 

Now, Vol II is being published in two volumes, viz. Cryogenic Engineering: Software solutions – Vol II A and Vol II B. Vol–II A contains the background theory, definitions and formulas and the problems solved with Engineering Equation Solver (EES). Vol II B contains problems solved with Mathcad. So, it is advisable that one refers to both the parts II A and II B.

In this book, i.e. Vol II A: first, a thermodynamic background for cryogenic liquefaction is given. Next, various cycles for liquefaction of gases are explained and the calculation formulas for the pay-off functions are given. Finally, various types of heat exchangers, hear transfer correlations, calculation formulas and graphs for analysis by LMTD and NTU methods are given. And, Second Law analysis of the cryogenic systems is explained briefly.

Some data on commercial liquefiers for Air, Hydrogen and Helium are also given.

Many numerical problems are solved to illustrate the ease of computer calculations using Engineering Equation Solver (EES).

Useful data for Nitrogen, Hydrogen, Helium, Argon, Methane, Fluorine and Oxygen are generated from NIST website.

EES has built-in functions for properties of several gases, refrigerants and fluids (including cryogenic fluids). Therefore, it is very convenient to use EES in these calculations.

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

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

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.
