Objective
Turbulent mass and heat transfer phenomena have a fundamental importance in many chemical, electrochemical and biochemical engineering processes as well as in heat exchanger modelling and environmental sciences. These phenomena are often predicted by rather obsolete models. But modern trends in engineering sciences indicate an urgent necessity to use modern hydrodynamic theories and instrumentation to predict mass and heat transfer phenomena in complex situations.
The goal of this project is to provide some hydrodynamic, heat and mass transfer measurements in turbulent flows with a complex geometry, for example in turbulent flows with separation, in order to test the classical form of the Reynolds analogy and to elaborate new types of momentum/heat/mass transfer analogies suitable for engineering applications. The concrete application of the analogies study will be the calibration of the numerical code for atmospheric pollution above towns, where the flow configuration can be simulated by separating and re-attaching flows downstream of the backward-facing step. The advanced electrodiffusion technique, which is suitable for measurements in the near wall region, will be combined with the thermo-anemometer method.
A new construction of the electrodiffusion and thermo-anemometer sensors will be elaborated and the original data treatment procedure will be used. These sensors will be sensitive to instantaneous flow direction. This will allow for their use under large flow pulsation conditions which can take place near the flow separation point, thus obtaining the necessary information about momentum/mass/heat transfer in this zone.
