The case study for heat transfer simulations is the first stage rotor blade of a mechanical drive gas turbine, which has complicated internal cooling passages. 0000041854 00000 n The Computer-Aided Design ("CAD") files and all associated content posted to this website are created, uploaded, managed and owned by third party users. 0000002378 00000 n This case represents airflow through a rotationally periodic gas-turbine stator. Measurement was performed using a coordinate measuring machine equipped with a touch trigger probe. Additive Manufacturing is a process that builds parts layer-by-layer from sliced CAD models to form solid objects. The key point data for the turbine blade obtained from the measurements is used to create areas using the splines and lines options Fig 1(a) shows the first step of this process.
