Heat Transfer and Fluid Flow Laboratory
Laboratory is one department of the Brno University of Technology, Czech Republic. Our research is oriented towards
Thermal inverse tasks were developed for numerical models of material and heat transfer behaviour. There are three main interests of the laboratory: cooling in metallurgical industry, polymeric hollow fibre heat exchangers, and separation processes.
Three major types of stands are used for a research for metallurgical industry: stand for cooling of rolls in hot rolling, stand for cooling of flat and long products in hot rolling and stand for study of cooling in secondary cooling area of a continuous casting machine. A large experience of the laboratory is concentrated on the determination of heat transfer boundary conditions at hot surface cooling with the application in continuous casting, hot rolling and hydraulic descaling. A great number of long term projects with industrial partners has been established (Lechler Germany, US Steel Košice, Posco Korea, Alcoa USA, ArcelorMittal, Vítkovice Ostrava).
The laboratory has been investigating polymeric hollow fibre heat exchangers for more than ten years. During that time, it became one of the leading experts in this field acting as an advisory board for industrial companies. Polymeric hollow fibre heat exchangers represent the heat exchanger (HE) of 21st century. They can replace commonly used metal HE. They are able to save up to 70% of weight in comparison with the metal one. Although, they find their place in processes connected with extreme conditions, they are mainly developed as cheaper alternative of metal HE for any application. And moreover, they are environmentally friendly and recyclable.
In 2012, the laboratory started to study separation processes. The research is focused on environmental chemical engineering processes including membrane separations (air/liquid filtration, membrane contactors, hollow-fiber membranes and filtration materials testing), absorption processes (separation of gaseous pollutants using wet scrubber), adsorption and water treatment. The research further includes preparation and characterization of filtration membranes based on geopolymers and alkali-activated secondary materials (fly ash and blast-furnace slag), preparation and characterization of ultrafine powder materials. Last it is health risk assessment of air, water and soil pollution. This includes risk analysis of airborne particulate matter and bounded harmful substances such as heavy metals, polycyclic aromatic hydrocarbons etc.
The laboratory is participating in the solution of national and international research projects, e.g. Czech Grant Agency Ministry of Education, Youth and Sports. The students of both regular and doctoral study are involved in the laboratory research when processing their theses.
