摘要

In the current Software Engineering Module (SEM-4) new physical model implementations have been tested and additional complex test cases have been investigated with the available models. For all validation test cases it has been shown that the computed results are grid independent. This has been done by systematic grid refinement studies. No grid independence has been shown so far for the Aerospatiale-A airfoil, the draft tube flow, the transonic bump flow and the impinging jet flow. Most of the main objectives of the current SEM, cf. Chapter 1, are fulfilled. These are the verification of the alternative pressure-strain term (SSG-model), the implementation of a swirl correction for the standard-(kappa)-(epsilon) turbulence model and the assembling of additional test cases. However, few results are available so far for the industrial test cases. These have to be provided in the remaining time of this project. The implementation of the Low-Reynolds model has not been completed in this SEM as the other topics were preferred for completion. Additionally to the planned items two models have been implemented and tested. These are the wall distance equation, which is considered to give an important part of a low- Reynolds model implementation, and the (kappa)-(omega) turbulence model. (orig.)
