Abstract
A passive flow modulation device (36) according to an embodiment includes: a temperature sensitive element (54) disposed within a first area (30); a piston (60) coupled to the temperature sensitive element (54), the piston (60) extending through a wall to a second area (44), wherein the first area (30) is at a higher temperature than the second area (44); and a valve arrangement (42) disposed in the second area (44) and actuated by a distal end portion of the piston (60), the valve arrangement (42) tangentially injecting a supply of cooling air (32) through an angled orifice (34) from the second area (44) into the first area (30) in response an increase in temperature in the first area (44). A passive flow modulation device (38) according to another embodiment comprises: a temperature sensitive element (78); a piston (86) coupled to the temperature sensitive element (78), the piston (86) including a head section (90), wherein the temperature sensitive element (78) and the piston (86) are disposed in a first area (30); and an orifice (34), extending from a second area into the first area (30), for supplying a flow of cooling air (32) from the second area to the first area (30), wherein the first area (30) is at a higher temperature than the second area; wherein the temperature sensitive element (78) enlarges or contracts to selectively position the head (90) of the piston (86) over a portion of the aperture (34) to control the flow of cooling air (32) from the second area into the first area (30). A corresponding turbine cooling system comprising a passive flow modulation device is also provided.
