Critical conditions for thermal explosion in the flow of a viscous fluid in a finitelength channel
Abstract
A simplified model of thermal equilibrium in a zerodimensional formulation is studied for the flow of a viscous reactive fluid in a channel of finite length, where viscosity and reaction rate are assumed to be exponential functions of temperature and where feed of the material takes place either at constant pressure differential or at constant flow rate. In an analysis based on the construction of Semenov curves, conditions for critical heating are derived.
