Conversion of ARO-1 to an Implicit Navier-Stokes Solver
Abstract
The purpose of this report is to describe the development of an implicit Navier Stokes solver (KM1) based upon modification of an existing explicit Euler code known as ARO-1. The report narrates the steps of the conversion, relates the lessons learned along the way, and highlights the algorithm's advantages and shortcomings. The goal upon inception of this work was to develop an efficient Navier Stokes solver, capable of solving complex three dimensional (3 D) internal flow problems in the Engine Test Facility of AEDC. It was to be modeled after the ARO-1 code because of ARO-1's established flexibility and robustness. While the KM1 code successfully solved the flow problems that were tried, it does not have the anticipated robustness that was expected. Considerable user interaction was required to obtain solutions for certain complex 3=D problems. The code has taken a backseat to a more robust code recently acquired. The KM1 code is still in its developmental form, and there are no plans for converting the code to a production format.
