TLDR
The linearized NavierStokes equations play a central role in describing the unsteady motion of a viscous fluid inside a porous tube and asymptotic solutions of these equations have been found.Abstract:

Fundamentals of Hybrid Rocket Combustion and Propulsion
TL;DR: In this paper, a review of Solid-Fuel Regression Rate Behavior in Classical And Non-Classical Hybrid Rocket Motors is presented. But the review is limited to the following:
Journal ArticleDOI
Biglobal linear stability analysis of the flow induced by wall injection
TL;DR: In this paper, the hydrodynamic stability of the flow in a solid rocket motor is revisited using a general linear stability approach, where a harmonic perturbation is introduced into the linearized Navier-Stokes equations leading to an eigenvalue problem posed as a system of partial differential equations with respect to the spatial coordinates.
Review of Solid-Fuel Regression Rate Behavior in Classical and Nonclassical Hybrid Rocket Motors
TL;DR: In this article, a modified blowing parameter was proposed for the Arrhenius preexponential constant, where the parameter exp(q′′ r/(Gcf /2) c ) is defined as the skin-friction coefficient of the gas isobaric specific heat.

Higher Mean-Flow Approximation for Solid Rocket Motors with Radially Regressing Walls
TL;DR: In this article, the velocity, pressure, vorticity, and shear of a circular-port rocket motor are modeled using a rotational, incompressible, and viscous flow model that incorporates the effect of wall regression.

Rotational axisymmetric mean flow and damping of acoustic waves in asolid propellant rocket.
TL;DR: In this article, the authors used the solution for potential flow subject to the boundary conditions of no flow through the head end and uniform speed normal to the burning surface, and the result for the Mach number in a cylindrical chamber is
