摘要

Abstract

In this study

rheological examination of the mixture of a tubular reactor in which methyl methacrylate was polymerized has been studied. The

(flow behavior index) value of Power Law Model of mixture contained in the reactor has been determined within the span of 0.3492 to 0.9889 by curve fitting. Employing these numerical data for velocity profile

the reactor has been modeled. Moreover

the functions of the reactor have been compared in the three modes of plug

mixed and laminar flow. The results obtained in this research indicate that the polymethyl methacrylate mixture contained in the reactor is pseudo-plastic. Moreover

as the conversion grows

the velocity profile starts as a parabolic profile and approaches the plug mode; although it never reaches the plug. The other conclusions borne in this study indicate that when the reactor's radius is decreased

the conversion rate grows. However

as decreasing the radius would also reduce the productions rate

this procedure is not economical. Finally

in this modeling

the amount of conversion is equal to 56.47% at the end and according to its laboratory proportion which is 55.88%

it has reached the conclusion that the modeling d

uly undertaken is applicable and valid.
