Abstract
Wind tunnel experiments were conducted to provide informations for the behaviour of full coverage film cooled surfaces with holes injection in boundary layers with emphasis on the utlization in modern gas turbines . separate test models were designed to simulate the turbine blade surfaces .
relation between pitch/diameter ratio and the blowing rate have controlled by the limitation of the mixing process between the cooling jets with the mainstrream and the interaction of the jets with another .
