A new rotor material is to be tested at very high temperatures,with a certain uncharacteristic thermal criteria, in order to predict temperature distribution under transient conditions. An analytical method of estimating transient temperature distribution across rotor segment cross-section is attempted. In addition, results are obtained from Autodesk Computational Fluid Dynamics simulation software. A 3D model of rotor segment is generated in Simstudio tools. New material properties are specifically generated in the CFD simulation database, input, boundary conditions are provided, model is meshed and requisite time step and solver conditions are applied. The CFD motion module is also associated for rotational effects. Analysis is carried out to obtain results. Key Findings: Transient coupled conduction and radiation effects are analyzed in CFD for the rotor segments in relation to the fluid flow parameters. The results provide an insight into the variations necessary in heater operation and surface flux,to achieve systematic surface and rotor core temperature parameters. On evaluation, results obtained analytically and from CFD approach are found to match closely, validating the methods.
