Mathematical modelling of nonstationary processes in the channels in the presence of chemical reactions in the coolant

Unsteady chemically reacting coolant flow in channels can be described by differential equations. Proposed are one- and two-dimensional mathematical models based on the generalized transfer equation to study the transients in the channels with constant and variable flow area in the wide range of the coolant velocity variations. The models are dimensionless. The results of calculation are given upon nitrogen tetroxide flow The results of ca culation are given upon nitrogen tetroxide flow. The results o the theoretical study base on the one-dimensional mathematical models are in good agreement with the experimental data
