Buffet boundary estimation using a harmonic balance method

نویسندگان

چکیده

In this work, the application of harmonic balance technique is demonstrated for transonic buffet cases. The method represents an alternative to time-marching simulations that are expensive complex flow Here applied on different test cases with inherently unsteady flows, i.e. two aerofoil configurations undergoing buffet. A gradient-based, variable time period used estimate frequency oscillation flows where it not know a priori. reduced computer costs respect marching allowed embed computation simple procedure boundary estimation. aim improve prediction coming from criteria based results steady computations, still popular in industry.

The Harmonic Balance Method

The harmonic balance method is used in most current commercial RF simulation tools. This is due to the fact that it has certain advantages over other common methods used in SPICE, namely (modified) nodal analysis (MNA), which make it better suited to simulate stiff problems and circuits containing transmission lines, nonlinearities and dispersive effects. In this project, the harmonic balance a...

Optimal Estimation of Harmonic Components Using ISFLA

In this paper a novel method based on evolutionary algorithms is presented to estimate the harmonic components. In general, the optimization of the harmonic estimation process is a multi-component problem, in which evaluation of the phase and harmonic frequency is the nonlinear part of the problem and is solved based on the mathematical and evolutionary methods; while estimation of amplitude of...

Rotor Flow Analysis using Animplicit Harmonic Balance Method

This paper is an extension of a previous work where a diagonally implicit harmonic balance method was developed and applied to simulate oscillatory motions of pitching airfoil and wing. A more detailed study on the accuracy, convergence, and the efficiency of the method is carried out in the current paperby varying the number of harmonics in the solution approximation. As the main advantage of ...
