Ashok Malhotra Edit Profile

consultant , Engineering educator

Ashok Malhotra, Indian engineering educator, consultant. Recipient, Knights of Columbus Mahindra Trust, India, 1974; fellow, University British Columbia, 1975-1978. Founder, trustee Jaipur Intellectual Foundation.


Malhotra, Ashok was born on July 20, 1950 in Pune, India. Son of Anand Prakash and Nand Rani Malhotra.


He is the brother of Lt. General Anoop Malhotra He graduated from the Indian Institute of Technology in 1971 with a degree in Mechanical Engineering. His Ph.D. Thesis was on supercritical carbon dioxide.


Dr. Ashok Malhotra received a doctoral degree in Mechanical Engineering from the University of British Columbia, Canada in 1978. He has been on the faculty of the Indian Institute of Technology, Delhi, The University of British Columbia Canada and the University of Mosul in Iraq. His most recent appointment during 2009–2010 was as the Director of the Amrapali Institute of Technology and Sciences in the Nainital District of India\r\n.\r\nAshok Malhotra has had special interests in supercritical fluids.

He has also worked on the optimal design of power plants using supercritical steam and written a book on supercritical steam. Following is a quotation on it by Christopher Mims,\r\n“Supercritical steam has already been used in coal-fired and nuclear power plants. The mechanism by which it yields higher efficiency is complicated, but ultimately it boils down to this: steam turbines need very hot steam in order to produce power, and supercritical steam is much closer to this temperature than cooler steam, says Ashok Malhotra, who literally wrote the book on the subject (Thermodynamic Properties of Supercritical Steam)” Christopher Mims\r\nThe Turbulent Prandtl number is a non-dimensional parameter required in convective turbulent heat transfer calculations.

The simplest model for turbulent Prandtl Number is the Reynolds analogy, which yields a turbulent Prandtl number of unity however based on. From experimental data based on air or water adjustments have been made to values slightly different from unity. Its counterpart the Prandtl number is employed in laminar flow calculations.

However, most flows in nature are turbulent rather than laminar and therefore incorporating the use of turbulent Prandtl Number becomes necessary. Its use can be entirely bypassed through more complicated and advanced heat flux modelling but challenges still remain in its formulation. Ashok Malhotra and Kang (1984) showed through calculations in a circular pipe that the is not close to unity but rather a strong function of the moleculer Prandtl number amongst other parameters.

They developed relationships between the turbulent and moleculer Prandtl number that can be employed in convective heat transfer calculations. Their work has been substantiated by other researchers e.g. McEligot and Taylor, 1996 and Churchill\r\nAside from his professional interests in higher education, science and technology, Ashok Malhotra's interest range from the environment to the economy.

From ancient history to philosophy. He regularly shares his views on such topics with the wider online community through his blogs. He has also authored a novel and a novella that elaborate his environmental and philosophical views through the medium of fiction.
