Abstract
In this work, we study the influence of orientation on the stability conditions of the
reaction front where the monomer is solid and the polymer is liquid. The mathematical model
includes the heat equation, the concentration equation and the Navier–Stokes equation under the
Boussinesq approximation. We use the method proposed by Zeldovich and Frank-Kamenetskii to
perform asymptotic analysis. We then perform a stability analysis. The linearized problem is
solved numerically using a multiquadric radial basis function method (MQ-RBF) to find the
stability boundary. This will allow us to deduce the influence of each control parameter of the
problem on this stability, in particular the angle of inclination of the experimental tube.
