Analysis of Combustion Instability in Liquid Fuel Rocket Motors [PDF]

open access: yes
The development of a technique to be used in the solution of nonlinear velocity-sensitive combustion instability problems is described. The orthogonal collocation method was investigated. It found that the results are heavily dependent on the location of

Existence and stability of limit cycles for pressure oscillations incombustion chambers [PDF]

open access: yes, 1983
In this paper, we discuss two problems. First, using a second order expansion in the pressure amplitude, some analytical results on the existence, stability and amplitude of limit cycles for pressure oscillations in combusticm chambers are presented.

Combustion of Agricultural Biomass - Issues and Solutions

open access: yesTransactions of FAMENA, 2018
Biomass is one of the oldest energy source known to mankind. Progress made so far in understanding of a rather complex direct combustion process allowed for a constant technology development. Increasingly stringent environmental requirements of the EU, especially in terms of the pollutant emissions, require development of new design solutions of the ...

The prediction of nonlinear longitudinal combustion instability in liquid propellant rockets [PDF]

open access: yes
An analytical technique was developed to solve nonlinear longitudinal combustion instability problems. The analysis yields the transient and limit cycle behavior of unstable motors and the threshold amplitude required to trigger a linearly stable motor ...

Comparison of approximate and numerical analyses of nonlinear combustion instability [PDF]

open access: yes, 1974
At the present time, there are three general analytical techniques available to study problems of unsteady motions in rocket motors: linear stability analysis; approximate nonlinear analysis, founded on examining the behavior of coupled normal modes; and
