RotCFD: A Viscous Design Tool for Advanced Configurations
The incorporation of viscous analysis in design is vital for a completeunderstanding of aerodynamic problems.This proposal offers to develop and integrate with RotCFD a method for semi-automatically generating grids suitable for viscous
analysis on complex configurations as well as parallelize the solver in RotCFD to take advantage of today's
The principle idea behind the semi-automation of the grid generation is to divide the geometry surface into patches and
generate body-conforming grids from these patches.
This partitioning allows for automatic generation of grids with
aspect ratios suitable for viscous flows.
Convection dominates the outer region, so unstructured Cartesian meshes
can be generated quickly and easily here.
The outer grid will be conformed to the inner grid so the entire grid
can be treated as one unstructured grid with an unstructured
solver, or as a hybrid grid with multiple zones and solvers.
In the hybrid approach, viscous solvers can be used for the inner zone
while the faster inviscid solvers can be used in the far-field.
In Phase I a proof-of-concept grid generator, and a conceptual methodology for solver
parallelization will be developed and demonstrated to work with RotCFD the
rotor aerodynamic design tool.
In Phase II, the features of the grid generator and solver will
be fully developed and expanded.
