| Scope of work: |
Project:Calculation of heat transfer in a fluid flow passing through an annular space between a rotating Turbine disk bore and an inner rotating shaft (fig 1) is of critical importance to gas-turbine designers for turbine disk lifing calculation purposes. Common approach for predicting convective heat transfer coefficient between fluid and disk bore is based on application of literature-based convection in a duct correlations relating the non-dimensional heat transfer coefficient (Nusselt number Nu=hd/k) to the flow Reynolds number(Re=ρVd/µ) in which h is the heat transfer coefficient, d is the hydraulic diameter of the annular space between the disk bore and the shaft [d=2(Ro-Ri)] and V is a characteristic velocity of the fluid flow. The purpose of current project is to design, build and validate a rig to generate data for developing convective heat transfer correlations between two concentric rotating cylinders of finite length (4
Scope:The test rig is comprised of two concentric co or counter rotating cylinders with air flowing at certain prescribed mass flow rate m (lb/s) through the annulus; m can vary in the range 0.01
