DISTRIBUSI STREAM FUNCTION DAN VORTISITAS FLUIDA PADA RUANGAN PERSEGI PANJANG YANG DIGERAKKAN OLEH DINDING YANG SALING BERHADAPAN

Y. B. Lukiyanto

Abstract


The form of fluid flow depends on many factors such as the fluid type and the channel form. Using computational technology, the distribution of vorticity and the stream function of a certain fluid type and a certain channel form can be computed such that the form of fluid flow can be predicted. This paper discusses incompressible fluid flow which is generated by a face-to-face rectangle wall that moves on opposite directions. By changing boundary values, the distribution of vorticity as well as the stream function of fluid flow on several variations of rectangle spaces can be computed. The similarities as well as the differences of fluid flow on those spaces can also be identified.
