Rhomboid Concave and Convex Dimples Applied for Cooling in Gas Turbines

Galina Ilieva [3]


Abstract: The scope of this work is to contribute towards a more efficient design of cooling platforms for gas turbines. Concave and convex schemes of rhomboid dimples, arranged irregularly along a cooling channel, are numerically modeled and studied for their effects on heat transfer and cooling effects of turbine blades. Research is fulfilled in Gambit and Fluent, based on a mathematical model and specified boundary conditions for modeling of aero- and thermodynamic characteristics of flow of coolant passing through cooling ducts. The proposed design and arrangement of dimples is found to be very promising and effective for cooling in gas turbines and other industrial applications.
