Abstrakt CZ: Je-li svazek trubek ve vymeniku vystaven pricnemu proudu vzduchu, dochazi pri urcitych rychlostech k jeho rozkmitani. V tomoto clanku navrhujeme jeden nelinearni model tohoto jevu a zabyvame se jeho kvalitativnim studiem. Abychom pracovali s realistickymi hodnotami parametru, identifikujeme parametry z namerenych dat.
Abstrakt EN: If heat-exchanger tube array is subjected to cross-flow, fluid-instabilities occur for some range of velocities causing possible damage. We propose one model of this phenomena. We also provide its qualitative analysis including stability and bifurcation of solutions. In order to use realistic parameters in our model, we fit our model to measured data.
