Hydrodynamic Simulation of Fluid Flow Around the Moving Solid Particles
Havlica, Jaromír ; Trávníčková, Tereza ; Kohout, M. ; Růžička, Marek
The hydrodynamic simulations of the incompressible viscous fluid around the solid particles has been focused on in this work. The hydrodynamic interactions between the moving objects and the fluid were calculated by the immersed boundary method (IBM).

Pattern Formation and Chaotic Dynamics in a Cross-Flow Catalytic Converter with Kinetics of Detoxification of Exhaust Gases
Kohout, M. ; Hadač, O. ; Havlica, Jaromír ; Schreiber, I.
In this contribution, the range of patterns occurring due to interaction of transport and reactions characteristic of the three-way catalytic converter (TWC) have been explored. We examined whether and how spatiotemporal structures such as spatially nonhomogeneous steady states and travelling waves are produced. Furthermore we found that the system displays a wide variety of chaotic spatiotemporal patterns, which were examined in detail.

An Immersed Boundary Method for Flow Simulations Around Stationary and Moving Rigid Particles
Havlica, Jaromír ; Trávníčková, Tereza ; Kohout, M. ; Růžička, Marek
The main aim of this work was study of the particles motions and interactions by the evaluation of particles positions, velocities and accelerations. It was shown that immersed boundary method is able to successfully describe interactions between particle and fluid, the interactions between particle and particle and interactions between particle and wall. The results were quantitative compared with other studies.

Modelling of Mechanical Interactions of Particles in Disperse Solid-Fluid Systems
Barczi, T. ; Kohout, M. ; Hadač, O. ; Havlica, Jaromír
One of the possible ways for mathematical modelling of mechanical interactions of particles in disperse solid-fluid systems is based on ballistic deposition methods and discrete element methods. In this contribution both of these approaches are examined and discussed their advantages and disadvantages in more detail.

Recent Advances in Outdoor High-Density Cultivation of Novelty Micro-Algae Strain with High Content of Lipids
Kaštánek, Petr ; Kaštánek, František ; Cepák, Vladislav
The objective of the study was the pilot plant examination of a newly developed integrated process for autotrophic cultivation of useful micro-algae. The process utilizes waste carbon dioxide as a source of carbon and yields simultaneously products that can be utilized in food and cosmetic industries, turned into biodiesel and/or used as a supplement in animal feed. At present, the cultivation of micro-algae merely for the production of biofuels is not economically viable. In the proposed process, the economy is improved by complex utilization of the micro-algae for simultaneous integrated manufacturing of several products that may be priced at different levels. In this way, the overall economy of the process is positive.
