Department D 2 - Thermodynamics

Thermodynamics is the study of the conversion of heat energy into different forms of energy (and visa-versa) and its relation to macroscopic variables. The modern thermodynamics has broad, interdisciplinary character and reaches out to various fields of physics, chemistry, biology, meterology etc.

In our laboratories we study the thermophysical properties of interesting fluids such as new, eco-friendly refrigerants or ionic liquids, the changes of state of matter or phases of solid matter, such as nucleation in condensation and cavitation, synthetized and impinging pulsatile jets, blood circulation, flow in elastic blood vessels, thermodynamic aspects of chemical reactions in the human body and friction properties of joints and joint protheses. The results find application in power engineering, research of atmospheric aerosols, pump erosion prevention, microfluidics, cooling of small devices,  control of large flows using tiny efforts, biomechanics and medicine.


Global instability of the rotating disk boundary layer

Lecture - May 19, 2010, 10:00 -11:00 Wednesday
Prof. Jonathan Healey, Keele University, Anglie

When a disk rotates at constant angular velocity in otherwise still fluid a boundary layer flow is established close to the disk. Obviously the local velocity of the disk increases with radius, but to a first approximation, this radial variation of the basic flow can be neglected to produce a "local" parallel-flow linear stability theory.  »»» 

Assessment of Physical Activity of a Human Body with Consideration of the Thermodynamics System

Lecture - February 9, 2010 (Tuesday), 10:00 -11:00
Dipl.-Ing. Philipp Rauschenberger, Institut für Thermodynamik der Luft- und Raumfahrt, Universität Stuttgart, Germany

Abstract: Model of the human cardiovascular system is applied for the quantitative evaluation of the human activity. The entropy production was used as a relevant quantity. The comparison with the ergonometric tests is shown.

Presenter: Dipl.-Ing. Philipp Rauschenberger

"Introduction to Fractional Calculus" is a forthcoming free-of-charge course offered by prof. A. I. Fedorchenko. The objective of the couse is to provide its participants with the background necessary for the understanding of the fractional calculus. The lectures will be given in English in the Institute of Thermomechanics ASCR, v. v. i.. The dates and times will be announced at a later date based on the response received.  »»»
