CEAS Professor Raj Manglik, PhD, served as the Plenary Keynote Speaker at the ASME’s 2013 Summer Heat Transfer Conference in July and received a 75th Anniversary Medal for his service to the heat transfer community and for his contributions to the field.
The American Society of Mechanical Engineers (ASME) presented Professor Raj Manglik, PhD, with the 75th Anniversary Medal of the ASME Heat Transfer Division during July’s Summer Heat Transfer Conference.
The award recognizes professor Manglik’s outstanding achievements in mechanical engineering spanning his seminal research contributions and service to the heat transfer community and ASME.
Manglik also served as the plenary keynote speaker at this year’s ASME conference where he presented “A Pathway to Sustainability: The Enduring Relevance of Enhanced Heat Transfer” and discussed energy conservation as it relates to heat and/or mass transport processes.
“We live in a world which is completely energy-centric. Whatever we do, our daily living, our economic well-being depends on energy – from cooking food to driving,” said Manglik. “Availability of energy, at least conventional energy, not electricity but how you produce electricity, for example, by using coal, gas, oil and nuclear fuel, all of that is limited. There is a finite amount available.”
In explaining the crux of his presentation, “The imperatives of sustainability warrant the mitigation of both energy consumption and environmental degradation. The efforts to achieve these goals are perhaps most acutely underscored by the need for not only conserving primary energy resources, but also their conversion, utilization, and recovery in every industrial, commercial, and domestic application.”
Manglik says that there is no simple solution to what he describes as a catch-22 cycle of energy consumption. “Thermodynamically, the very simplest principle is that in any engine no matter what you do with it, what fuel you put in you will only get a small portion of that out as useful energy or work – and a lot of energy is wasted. No matter what, there is going to be what we call thermodynamic warming because this consumption of energy, which is converting one form of energy to another, has heat and other energy losses which are inevitably leading to thermodynamic warming,” he explains. “Even if we are burning clean coal – that requires an enormous amount of energy just to make the coal clean. (1) You’re burning some other energy to clean coal because you (2) can burn the coal for energy (heat). It’s like a Pac-man of energy use and loss as each step releases more waste energy and there’s no escaping this.”
He believes that the engineering community should continue to make strides by jumping into the energy crisis debate. “As engineers we need to find better ways to run this energy engine so that it is a little more efficient,” he said. “The idea is to conserve and transform through less [energy] dependency.”
During his presentation Manglik also talked about making improvements in the boiling and evaporative process. “The fundamental work we’ve been doing here at UC is thermal performance enhancement of phase change and evaporative processes,” he said. “Boiling and evaporative processes are used in a large number of engineering devices. The most commonly known is the power plant boiler that produces steam and some of our research here is to improve the boiling heat transfer so steam can be generated with less energy input.”
Professor Manglik has been with the University of Cincinnati since 1991 and been working in the field of enhancement of heat and mass transfer for more than 29 years. He has held several prestigious scholarly journal editorial positions, and currently serves as the Editor-in-Chief of the Journal of Enhanced Heat Transfer.
He says his future plans are to promote significant energy efficiency research. “We need to come up with the science and engineering for devices and systems that are much more energy efficient,” he said. “Why do we need to be energy efficient? “[Because] it is a crisis and the only question about this crisis is that ‘is the catastrophe going to happen in 20, 200, or 2000 years’?”
