<p>An improved cooling system utilizing flow resistant devices to distribute liquid coolant to air foil coolant channels formed in a bucket of a turbine is disclosed. A separate flow resistance device is associated with each of the air foil coolant channels so as to meter the flow of liquid coolant into the coolant channels. In the disclosed embodiments, the flow resistant devices alternately take the form of a tortuous passage, an orifice and a plurality of vortex flow chambers. <IMAGE></p> |
