Method for enhancing heat transfer inside a turbulated cooling passage

摘要

A method of enhancing heat transfer and cooling efficiency in a cooling passage (10) includes forming a plurality of turbulator rings (14) in the passage, the rings projecting inwardly, substantially perpendicular to a cooling flow direction in the passage; and using a patterned electrode (16), forming at least one gap (22) in one or more of the turbulator rings, extending substantially parallel to the flow direction.
