Abstract: This paper presents a method for predicting the variation of the velocity and length scales for plane and circular turbulent jets issuing into co-flowing streams. The basis of this method is an assumed variation in the turbulence production integral in the transition region from the strong jet to the weak jet. The solution is built around the integral momentum and energy equations. The predictions from this method agree well with the experimental results for both plane and circular jets.
