For an approximate calculation of the bounded jet flow, a velocity distribution function on the bounded jet center-plane is proposed, considering the effects of the wall turbulence and the free turbulence. Also, in order to determine the empirical parameter contained in this function, experiments were carried out using a nozzle having an aspect ratio of 16 with the initial turbulence intensity prescribed. As a result, the velocity distributions of the bounded jet flow are well expressed by the proposed function, regardless of the initial turbulence intensity. Furthermore, the variation of the flow patterns towards downstream can be shown by means of the parameter contained in the function.
