Linear Flow Analysis for Turbomachinery

RPMTurbo is an engineering consultancy specializing in linear flow analysis for turbomachinery. Linear flow analysis is used to determine unsteady aerodynamics by linearizing the unsteady flow equations and then solving the equations in the frequency domain. This is 100 to 1000 times faster than conventional time-domain methods. Linear flow analysis can be used to assess the flutter risk of compressor blades, turbine blades and fan blades.

Flutter Analysis

Blade flutter is self-excited blade vibration due to the interaction of aerodynamic forces and blade forces. The long blades of large-scale turbomachinery such as steam turbines, gas turbines and aircraft engines can suffer from blade flutter. Flutter can have a significant economic cost due to increased development costs, losses due to development delays and increased maintenance costs. RPMTurbo provides manufacturers of turbomachinery with high quality flutter analysis based on 3D viscous unsteady flow simulations in a short time-frame (weeks not months) that helps to identify potential flutter problems earlier in the design process.
