Flow Through Gas-Turbine Ducts

Existing computer program, Axisymmetric Diffuser Duct code (ADD code), modified to permit calculation of flows through small gas-turbine ducts with struts, guide vanes, and large degrees of turning. Code improvements include new coordinate generator, endwall loss model, and generalized geometry capability to describe struts and guide vanes in ducts that turn more than 90 degrees. Improved output format developed to provide solution on any arbitrary plane in duct.
