Objective
The main goal of the project is to improve our knowledge of airframe noise generation problem on the way of formulation and full resolving the test problems underlying the main mechanisms, which control the process. Combination of experimental, theoretical and numerical techniques will be used to address various topics:
(i) development of an adequate theory of the turbulence/rigid surface noise generation mechanisms, including viscous waves generated by boundary layer turbulence;
(ii) elaboration of new experimental technique and on this base
(iii) development of an adequate numerical methods which could be extended to careful prediction of noise generation mechanisms by landing gear and high lift devices;
(iv) attempt of attaining a more profound understanding of mutual interaction role of quadruple sources in separation zone (turbulent vortices) and dipole sources appeared on the rigid surface and of clarifying the reflection condition role in effectiveness of noise radiation.
As input to the future problem for next generation of aircrafts to meet the incoming regulations in the cabin noise we plan to estimate the role of the effects under consideration in the interior noise problem and formulate some ideas for noise control in aircraft cabin;
One of the main innovation objective is to develop low compressible numerical algorithm on DNS Direct Numerical Simulation and LES - Large Eddy Simulation of the turbulent flow streamlining the circular cylinder well describing the novel acoustical experiment for laminar and turbulent upstream flow. The main expected result concerns development of new methods for airframe noise diagnostics and determination of active and passive methods of airframe noise control based on synergy of theoretical, experimental and numerical approaches.
