  A WAY TO USE WASTE HEAT TO GENERATE THERMOELECTRIC POWER,

  In recent years there has been rising interest in thermoelectric generation as a potential source of electric power using waste heat. This paper describes thermoelectric power generation from waste heat from biomass boilers, utilizing generators that can convert heat energy directly to electrical energy. General principles of thermoelectric conversion and future prospects of these applications are discussed.

  This paper introduces utilization of the CFD technique for modeling of PM10 (particulate matter 10 micro-m) dispersion in urban areas, with focus on detailed description of processes in the ground surface boundary layer. The description of deposition and re-suspension processes is introduced and applied on the city-scale model of the city of Brno (pop. 400 000). The air threshold velocity of re-suspension was used as basic parameter for quantification of re-suspension. The particular value of the air threshold velocity of re-suspension was obtained from analysis of the long-term measurements carried out in the studied urban area and the subsequent small scale modeling of air flow in selected parts of the city-scale model.

  The work is focused on water falling film formation and heat transfer in atmospheric pressure. Different types of the tube s surface structure was experimentally tested, namely smooth surface tubes, ribbed tubes, fin tubes. The bundle of horizontal tubes in atmospheric pressure was used for parametrical studies focused on expression of horizontal tube spacing and falling liquid flow rate influence on falling film formation and heat transfer.

  Particulate matter dispersion modelling along urban traffic paths, Inderscience, Ltd
  journal article in Web of Science
  In this paper authors compare two different approaches of 10 m particles (PM10) dispersion modelling in urban areas. The study is focused on comparison of the Eulerian-Lageangian approach accurately describing particle aerodynamics and the passive scalar approach representing simplified alternative for description of dispersion processes. CFD code StarCD has been used for this study as appropriate tool capable of correct velocity field prediction and inclusion of both approaches. A street canyon with intensive traffic located in the central part of the city of Brno is used as a convenient study area. The numerical predictions obtained by both tested approaches are compared with an in situ measurement carried out in the studied street canyon. To simulate traffic, an original model developed previously by the authors is used that takes into account traffic density, speed of cars and number of traffic lanes.

  In this paper authors focus on determination of the threshold velocity of re-suspension for particles 10 m in an urban street canyon with two-way traffic. The urban wind threshold velocity of re-suspension is derived from a long-term measurement carried out in the city of Brno. A numerical modelling based on the finite volume method is used for a detail study of the relation between a wind velocity above buildings roofs and an air velocity just above the ground surface. The predicted threshold air velocity of re-suspension at the bottom part of the studied street canyon is compared with two theoretical studies on particle re-suspension. Calculations are carried out for perpendicular, longitudinal and oblique wind direction with and without inclusion of traffic dynamic. To simulate traffic, an original model developed previously by the authors is used that takes into account traffic density, speed of cars and number of traffic lanes.
