Research Studentship in Combined Forced and Natural Convection Heat Transfer in Steam and Gas Turbine Casing Cavities

Research Studentship in Combined Forced and Natural Convection Heat Transfer in Steam and Gas Turbine Casing Cavities

Supervisor: Prof Budimir Rosic

Details of Post

The project is aimed to investigate flexible operations of future conventional power generation plants in the increased presence of power generation from renewable sources. Rapid change of loads, frequent starts and stops will be the main characteristic of future fossil fuel power plants with a detrimental impact on turbine life. Therefore an improved prediction of the rotor and casing temperature field is required to minimise the thermal stresses and control the clearance between stationary and rotating components. To achieve these requirements an improved understanding of complex flow phenomena during different start and stop regimes is needed. These phenomena involve combined forced and natural convection heat transfer, transitional flows, and unsteady interactions. Numerical investigations will be performed using CFD and different advanced turbulence modelling strategies (LES, hybrid RANS-LES). The project will be done in collaboration with Mitsubishi Heavy Industries (MHI) and a simplified model of a steam turbine casing will be built and used as a platform for validation of numerical simulations. During the project, the design of turbine casing geometry will be optimised in order to improve flexible operation of power plants. The student will be a member of The Osney Thermo-Fluids laboratory and will be supervised by Prof. Budimir Rosic.
