The recuperative heat exchangers are an important part of the industrial plants. There are a number of such heat exchangers that differ in the arrangement of the streams. The knowledge of the flow arrangement of the streams is very important from a point of view of the heat exchangers calculations. There are various calculation methods, but only one takes into account the flow arrangement of the streams directly. The quantity that takes this into account is called the countercurrent index. The article deals with the determination of this quantity for a given recuperative heat exchanger.
