Abstract: Previous simulations of a turbojet disc cavity with full Navier-Stokes CFD and simplified geometry and boundary conditions have been improved to reduce the level of approximation. A new grid was built using a multi-block approach. The case was computed with a commercial Navier-Stokes solver, STAR-CD (CD-Adapco Group), on the latest parallel computing system available at the CSIR. The results are compared to those computed with an in-house developed 1-D flow solver coupled with a 3D conduction code, and thermal paint validation data. The aim of the paper is to review the approach to disc cavity analysis followed by the CSIR
