A multigrid Navier-Stokes CFD code for rotor computations

摘要

This paper presents the development of a multigrid Navier-Stokes code TLNS3DR for rotary wing calculations. The TLNS3DR is developed from the fixed-wing TLNS3D code by including a rotation term and making necessary modifications on boundary conditions. The TLNS3D code solves the thin-layer Nhavier-Stokes equations using an explicit multistage Runge-Kutta type of time stepping with multigrid Method. The TLNS3DR code reformulates the TLNS3D code in the rotor blade-fixed moving frame of reference and solves relative motion Of fluids.
