RISSolution Stabilization and Convergence Acceleration for the Harmonic Balance Equation System
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents an efficient approach for stabilizing solution and accelerating convergence of a harmonic balance equation system for an efficient analysis of turbomachinery unsteady flows due to flutter and blade row ...
Multi-Objective Aerodynamic and Aeroelastic Coupled Design Optimization Using a Full Viscosity Discrete Adjoint Harmonic Balance Method
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: With increasing requirements for high-loading and high-efficiency turbomachines, blades become thinner and thinner and thus design optimizations considering both aerodynamic performances and aeroelastic stability become ...
Three-Dimensional Unsteady Aerodynamic Optimization of a Transonic Compressor Stage Using an Implicit Discrete Adjoint Harmonic Balance Method
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The design of high-loading and compact modern turbomachines results in strong unsteady interactions between two adjacent blade rows, which has been found to have a noticeable impact on aerodynamic performances of turbomachines. ...
A Time–Space Multigrid Method for Efficient Solution of the Harmonic Balance Equation System
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this article, an efficient time–space multigrid (TS-MG) method for solving the harmonic balance (HB) equation system is proposed. The principle of the time–space multigrid method is to coarsen grids in both space and ...
