Review of the research on the turbulence in the laboratory for thermal engineering and energy

Abstract

Paper gives a review of the most important results of turbulence research achieved by the Laboratory for Thermal Engineering and Energy. Paper presents detailed overview of the history of the scientific research provided in the laboratory, from the beginning in the mid-60s to today, pointing out the main reasons initiating the investigations in this field. After the first period, which was mainly devoted to the research of the structure of the turbulence, since the beginning of the 80s, research is mainly oriented to the flows at high temperatures including chemical reactions and to the development and improvement of differential mathematical models as a modern and very efficient tool in the technological development. This research significantly contributed to the development of pulverized coal burners, plasma-chemical reactors, and optimization of pulverized coal fired boilers operating parameters and prediction of the greenhouse gases emissions. Most recent period includes experimental and numerical studies of the coherent structures in turbulent fluid jets, mathematical modeling of various turbulent thermal flow processes including two-phase turbulent flow in the multiphase heat exchangers and mathematical modeling of the atmospheric boundary layer.

“…In addition, the perfect gas equation of state was considered. For the closure of the system, three turbulence models are used [11,[15][16][17].…”

Review of the investigations of pulverized coal combustion processes in large power plants in laboratory for thermal engineering and energy: Part A

“…be later directed to study of the free flame flow, high temperature solid-state flows, and the low temperature plasma flow [1]. Under the leadership of the early deceased academician Dr. Zoran Zarić, mathematical models for the calculation of turbulent flowscooling towers plume, the spreading and mixing of hot water from the cooling systems of Thermal Power Plants -TPP, classic and nuclear, in rivers, lakes and seas, and models for calculation of thermal capacity of river basins were developed.…”

“…These studies continued and extended in the late 1990's and early 2000's into modern mathematical modelling of CFD of the all processes in the furnace. Part of this research has already been presented in [1], while the previously mentioned recent research will be presented in the next section which refers to the complex modelling of the processes in furnaces, as a base for process control in operation.…”

“…Boundary-layer turbulences models and scales as in [21] tested an autonomous design model called k-ε-θ 2 , which is useful for low Reynolds numbers and flows with particles and strong heat exchanging within boundary-layer. This model is not precise enough for high speed aerodynamics as in nozzle flows.…”
