Abstract
A contoured turbine airfoil assembly including an end wall () formed by platforms () located circumferentially adjacent to each other, and a row of airfoils () integrally joined to the end wall () and spaced laterally apart to define flow passages () therebetween for channeling gases in an axial direction. A trough () is defined between a pressure side ridge () and a suction side ridge () located forward of each pair of airfoils (). Each trough () has a direction of elongation aligned to direct flow into the flow passage () centrally between each pair of airfoils ().
