1. Alternative methods of building cooling under hot climate conditions

   In hot climatic zones, it is necessary to ensure appropriate indoor environment in buildings during major part of the year. Classic techniques, as forced cooling and/or air-conditioning, have considerable energy demands. For this reason, it is desirable to investigate alternative methods of inner environment conditioning, which are capable to decrease energy consumption. Many such methods - as utilization of double-skin solar façades, phase-change materials or solar chimneys in combination with night-time passive cooling, were investigated and developed in our department for conditions of Central Europe. However, their using under warm or hot climate conditions is questionable. The topic is therefore focused on judgment of applicability of various alternative methods of building cooling/conditioning in hot climate, comparison of their functionality and energy savings. The selected technique will be validated computationally and experimentally. The research will be carried out using numerical simulations (TRNSYS, CFD codes) and experimental investigation of real and/or model objects.

   Tutor: Pavelek Milan, prof. Ing., CSc.

4. Image processing in fluid mechanics problems and Environmental Engineering

   The aim is to develop programs based on the integrated development environment from National Instrument IMAQ image processing problems in fluid mechanics and environmental engineering. They will used of modern hardware components to enable parallel processing, such as multicore processors and FPGAs. Problems can be tackled flow visualization using smoke and bubbles (evaluation, geometry and homogeneous current fluctuations of movement, the current interaction with the environment, the application of 2D images, possibly in 3D) or detection of particles in the images of optical, phase-contrast and, if present. electron microscope: fibers, pollen, porous particles (determination of geometrical parameters: length, diameter, porosity, particle counting, classification).

6. Optimizing the parameters of the secondary cooling of continuous casting of steel

   The aim of the work will gain new knowledge from the water possibly air-water cooling nozzles for continuous casting of steel. The work will focus on research in the boundary conditions under cooling nozzles. The aim will be to develop a model of boundary conditions under the nozzle for a billet caster. Develop a tool for designing and optimizing the secondary cooling. It is expected that the results will be used in a foundry (TRZ and EVRAZ VÍTKOVICE STEEL)
