Abstract

The present work is an investigation of the steady state spherical reaction front that is accompanied by the substantial increase in liquid viscosity that is typical of polymerization. The normal rate of front propagation is taken as constant and is considered to be a parameter of the problem. Account is taken of the resistance at apparatus inlet and outlet, and of the hydraulic properties of the feed pump. It is shown that the local stream velocity at the front depends nonmonotonically on the front radius. Depending on the ratio of the problem parameters there are two, one, or no steady states of the front. The resistance of the steady states to a small disturbance in front radius was investigated.
