Verification of the POSCA Code Using Analytic Benchmark Examples

This paper describes a verification study of the POSCA code using analytic benchmark examples. The existing examples which have analytic solutions were adopted to verify the POSCA code. In this work, the verification study of the POSCA code was made using the existing five benchmark examples which have analytic solutions. It is believed that the tested examples can verify key physical behaviors modelled in the POSCA code. The comparisons of the POSCA results against the analytic solutions show very good agreements. Therefore, it can be concluded that the POSCA code solves its governing equations accurately and reliably. Validation study using experimental data is on-going for quality assurance of the POSCA code.
