dc.description.abstractNorint pasiekti idealią ventiliaciją svarbu pasirinkti tinkamą įrangą bei rėžimus ir žinoti energetinių augalų biomasės aerodinamines savybes. Tyrimai atlikti naudojantis specialiu aerodinaminių savybių tyrimų stendu. Žaliava iš pradžių buvo supjaustyta į kelių skirtingų dydžių pjaustinius ir užkrauta į ventiliavimo talpą. Stendo ventiliavimo sistemos pagalba į šią talpą buvo tiekiamas oras. Tiekiamo oro intensyvumas tam tikrais laiko periodais buvo didinamas. Tuo pačiu metu spiritiniu mikromanometru buvo matuojamas stati-nis slėgis, keliuose užraukto sampilo sluoksniuose. Taip buvo fiksuojami patiriami slėgio nuostoliai. Tokie patys tyrimai buvo atlikti kiekvienos frakcijos pjaustiniams. Atlikus šiuos tyrimus, žaliavos buvo užkrautos dar kartą, tik šiuo atveju sampilas buvo užslėgtas 50 kg svoriu. Taip buvo imituojamas 5 m aukščio sampilas, kuris po sampilo sudarymo savaime susislegia. Toks procesas įtakoja aerodinaminius pasipriešinimuslt
dc.description.abstractIn order to achieve perfect ventilation it is crucial to choose the correct equipment and modes. So it is important to know aerodynamic properties for energetic plants, changes in its tendency and influential factors. The studies were conducted with Artemisia dubia Wall. energetic plants. Research was carried in 2017 – 2018 at Aleksandras Stulginskis University. While using the special stand designed specifically to study aerodynamical resistance in raw material layers a research was carried out. Raw material was sliced into several different size chaffs. With a ventilation system air was blown into a cylinder shape capacity unit loaded with raw material. During short periods of time air intensity was increased. At the same time pressure losses were captured with a liquid micromanometer. It was done for every single group of chaffs. After that raw materials were loaded again and it had a weight of 50 kilograms putted on their top. This was to imitate a 5 me-ter height pile, which after some time naturally reaches a neutral point and the height of the pile does not change anymore. Such progress also affects the aerodynamical resistanceen
