Determination of the drag coefficient and shape factor for irregulator chips of energetic willow Salix viminalis
Języki publikacji
Abstrakty
W pracy przedstawiono pomiar czynnika kształtu i współczynnika oporu cząstek nieizometrycznych takich jak zrębki wierzby energetycznej. W celu wyznaczenia powyższych parametrów zaprojektowano i zbudowano aparat, w którym dane eksperymentalne otrzymano metodą aerodynamiczną. Uzyskano eksperymentalne zależności pomiędzy współczynnikiem oporu a liczbą Reynoldsa dla wszystkich badanych zrębków i uzyskano uśrednioną wartość sferyczności dla badanej mieszanki. Dla wszystkich badanych frakcji mieści się ona w zakresie 0.612-0.676.
The paper presents the results of experimental determination of the shape factor and drag coefficient of non-isometric particles like wood chips. In order to determine these parameters a specially constructed set-up was built. The experimental relationship between the drag coefficient and the Reynolds number for wood chips investigated was obtained altogether with the mean value of sphericity equals to 0.612-0.676.
