Název v původním jazyce

Using of CFD simulations for increasing speed and temperature of flame spray technology

Popis výsledku v původním jazyce

Quality and properties of the deposited coating are determined by depositing and solidification process conditions. So it is possible to influence coating properties by changing conditions of gas mixture flow, flame properties and material properties ofdeposited material. We know that it is vital to increase velocity of the flame and deposited particles to achieve some properties of the coating. The contribution contains description of CFD-simulations of the present state-of-art of flame-spray processand experimental validation of these simulations. Design of additional nozzles is presented and their impact on flow field and flame parameters is studied. Validated CFD model is used for performance prediction of these nozzles. Several variants are compared and the possibility of improvement of technology parameters is analysed. Heat transfer, chemical reactions a turbulent fluid flow are modelled. Comparison of computed results with experiment is presented as well.
