A flow control assembly for controlling cooling flow of a turbine engine is provided. The flow control assembly includes a first flow control device having a first sidewall and a second sidewall. The first sidewall is coupled to a compressor vane and is configured to define a first flow path from a compressor to a turbine vane. The second sidewall is coupled to a compressor vane and is configured to define a second flow path from the compressor to a turbine blade. A second flow control device is coupled to the compressor and includes an orifice device coupled to the compressor vane and a meter device coupled to the orifice, wherein the orifice is configured to direct a cooling flow to the meter device. A controller is configured to control the meter device to facilitate regulating the cooling flow into at least one of the first flow path and the second flow path.
