dcterms:description
By transport of some dangerous gases and liquids in chemical engineering is very important to detect a possible leak along the pipeline. The leak can be detected by a system which consists of special permeable detection pipeline placed very close to the main transport pipeline. In defined time cycles, the air column in the detection pipeline is sucked into the transported substance sensitive sensor. In this paper the simulation of transport of the hydrocarbons from the place of leak to the sensor is presented. The dispersion effect by transport was numerically simulated in Matlab. It was made a FEM - model of the perforated detection pipeline and this model was transferred using LMS method as linear state model to Matlab. Finally the simulation was compared with the data from an experiment.

Při transportu některých nebezpečných plynů a tekutin v chemickém průmyslu je velmi důležité detekovat případné úniky podél potrubí. Únik může být detekován systémem tvořeným detekčním potrubím, které je umístěno velmi blízko hlavnímu transportnímu potrubí. V definovaných časových cyklech je transportován vzduchový sloupec v detekčním potrubí k citlivému senzoru. V tomto příspěvku je představena simulace transportu uhlovodíků z místa úniku k senzoru. Efekt disperze vlivem transportu byl numericky simulován v Matlabu. Byl vytvořen také MKP model perforovaného potrubí a tento model byl přenesen pomocí metody nejmenších čtverců jako lineární stavový model do Matlabu. Nakonec byla simulace porovnána s experimentálními daty.
