Abstract

U ovom radu istraživala se raspodjela vremena zadržavanja u tri različite cijevi, ravnoj cijevi, cijevi sa staklenim kuglicama te spiralnoj cijevi koje opisuju hidrodinamiku strujanja u različitim tipovima cijevnih reaktora. Raspodjelu vremena zadržavanja je potrebno odrediti kako bi se na osnovu nje moglo utvrditi odstupanje promatranog sustava od idealnog strujanja. Eksperimentalni podaci dobiveni su unošenjem trasera koji predstavlja impulsni poremećaj u sustav te mjerenjem odziva na impulsni poremećaj. Iz eksperimentalnih podataka dobivene su RVZ krivulje. Obradom eksperimentalnih podataka dobivene su različite vrijednosti vremena zadržavanja i disperzijskog broja u trima cijevima.

Abstract (english)

In this experimental work, the distribution of time retention was investigated in three different tubes, flat tube, glass beads tube and spiral tube describing hydrodynamics of flow in various types of tubular reactors. The allocation of the retention time has to be determined in order to determine the deviation of the observed system from the ideal flow. Experimental data were obtained by introducing a tracer, which represents a impulse signal in the system, and by measuring the response to the impulse signal. From experimental data the RVZ curves were obtained. By processing experimental data, different values of retention time and dispersion time were obtained in three tubes.
