Check out the book on Pressure-Driven Microfluidics by our distinguished colleague V. Tesař, published by Artech House.
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.
In the stability theory of shear layers, the term `local stability' refers to the stability properties of a particular velocity profile at a given position in the flow. When the basic flow develops the streamwise direction, e.g. in a growing boundary layer, the changing local stability properties can be mapped out downstream. If there are regions of local absolute instability then there is the possibility of a `global instability' of the entire flow. When the basic flow varies slowly in the downstream direction the global stability can be determined from the local stability. »»»
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. »»»
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.

The team of scientists from the University of Sheffield, including Prof. Václav Tesař, have received the 2009 Moulton medal for their paper entitled On the design and simulation of an airlift loop bioreactor with microbubble generation by fluidic oscillation published in Food & Bioproducts Processing, 2009. The medal has been awarded anually by The Institution of Chemical Engineers (IchemE) since 1929 for the best scientific paper in the field. »»»
This seminar gives an introduction of the research activities in Prof. Darina Murray's heat transfer group at Trinity College Dublin, focusing specifically on synthetic jet impingement. »»»
"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. »»»
Dr. J. Healey graduated with a degree in physics at Oxford University in 1987, where he also obtained a DPhil in physics in 1991. His doctoral thesis was concerned with the analysis of phase spaces reconstructed from time series data. In 1991 he was appointed to a post-doctoral position in the Engineering Department at Cambridge University to work on the laminar-turbulent transition of boundary layers. In 1996 he was appointed first to a temporary lectureship in the Mathematics Department at Brunel University, and then to a lectureship in the Mathematics Department at Keele University. »»»
Main topics of the research of Dr. de Lange are the boundary layer transition, heat transfer and cooling in gas turbines and the thermodynamics and transient behavior of turbine/compressor systems.The flat plate boundary layer experiments in a water channel have been performed. »»»
As you surely know, prof. Ari Glezer is the originator of the term „synthetic jet“ and the founder of this particular branch of fluid mechanics. »»»
Abstract: While the field equations for complex fluids are usually formulated such that they respect the principles of nonequilibrium thermodynamics, the choice of »»»
