Milivoje Kostic

Professor Milivoje M. Kostic of NIU’s Department of Mechanical Engineering has been invited to deliver a plenary lecture at the fifth WSEAS International Conference on Heat and Mass Transfer.

The conference is held from Jan. 25 through 27 in Acapulco, Mexico, and is organized by the World Scientific and Engineering Academy and Society (WSEAS)

Kostic’s plenary lecture focuses on philosophical and practical aspects of energy, heat and entropy, with emphasis on reversibility and irreversibility, and a goal to establish the concept of ideal “reversible heat transfer,” regardless that heat transfer is a typical irreversible process.

Heat transfer, like any other energy transfer, can be achieved from any-to-any temperature level, and in limit be reversible, if temperature of an intermediary cyclic substance is adjusted as needed, using isentropic compression and expansion.

The reversible heat transfer limits are the most efficient and demonstrate limiting potentials for practical heat transfer processes. The heat transfer and thermal energy are unique and universal manifestation of all natural and artificial (man-made) processes, and thus are vital for more efficient cooling and heating in new and critical applications, including energy production and utilization, environmental control and cleanup and bio-medical applications.
