摘要：
Systems and methods for determining the flow distribution of a fluid through a component with a sensing cable including an optical fiber sensor array aligned with a heating element disposed in the component. An excitation source is configured to propagate at least one heat pulse through the heating element along at least a portion of the sensing cable to affect an exchange of thermal energy between the heating element and the fluid exposed to the sensing cable. An optical signal is adapted to receive a signal from each of a plurality of sensor locations and measure a temperature profile corresponding to the heat pulse at the sensor locations. A control unit is configured to determine a flow of the fluid by determining one or more properties of the fluid exposed to the sensing cable at each of the plurality of sensor locations based on the temperature profile corresponding thereto. The present invention can be effective in accurate and high spatial resolution of flow distributions through vessel components, su
