The current research study presents a numerical approach in modelling the conjugate heat transfer system of the gas-turbine rotating discs-cavities. The work was undertaken to understand such phenomena and, more specifically, to numerically investigate the thermal interactions in rotating discs-cavities. The developed solver is capable of dealing with complex heat transfer problems, such as unsteady three-dimensional compressible rotating-flows. The development was based on integrating an inhouse computational fluid dynamics code (SURF) with a heat conduction solver internally. Method of interpolation using mapped area was also introduced for treating non-matching meshes at interface, which plays an effective role in exchanging boundary data. This thesis also documents the development of a numerical finite volume cell-vertex hybrid edgebased heat conduction code by the author using FORTRAN. The heat conduction solver was developed and validated to deal with three dimensional solid-domains using unstructured elements. The validation process was carried out on several test cases for investigating the temperature distribution. The test results were presented to show good agreement with the analytical, experimental and other commercial numerical solutions where they exist.
