Совершенствование гидравлических характеристик камер сгорания ГТД методами вычислительной аэрогидродинамики и оптимизации

Abstract

Results of the gas turbine combustion chambers hydraulic characteristics improvement investigations by computational fluid dynamics methods are generalized. The investigations are performed on the next areas: the computational domain choice and the boundary conditions setting under three-dimensional simulation of the flow in the diffusers, their aerodynamical optimization, orifice discharge coefficients calculated evaluations target accuracy indices justification and the nonconformal block-structured grids with hierarchical structures application.
