The invention relates to an airflow separation detection method and system, and an airflow separation position detection method and system. The airflow separation detection method, the airflow separation position detection method and the like can detect whether airflow is peeled off from the surface of an object or not without reinstalling a sensor on the object or using an original sensor. In theairflow separation detection method, it is detected that separation, from the surface of the object, of an airflow flowing on the surface of the object is occurring, in a case where an absolute valueof a temporal variation rate of an electric power consumption value of the plasma actuator or an absolute value of a temporal variation rate of a current value of the plasma actuator is equal to or greater than a predetermined value, the temporal variation rate being a rate of variation relative to time, the electric power consumption value or the current value of the plasma actuator being measured under application of the alternating-current voltage having the predetermined voltage value to the plasma actuator. In the airflow separation position detection method, when the air current which flows on the surface of the object detects having exfoliated from the surface of the object using the airflow separation detection method, the air current detects having exfoliated from the surface ofthe object in the position of the plasma actuator which was the target of detection.
