Twodimensional and axisymmetric jet flows with finite initial cross sections
Abstract
In addition to the momentum integral equation, the energy integral equation of the boundary layer is used for an approximate calculation of the jet flows issuing from a finitewidth nozzle and from a finiteradius nozzle. The length of the zone of flow establishment, the width or radius of the jets and the centerline velocity are calculated. The eddy kinematic viscosity is assumed to be proportional to both the centerline velocity and the mean width or radius of the jets. This assumption means that the constant contained in the eddy kinematic viscosity is to have a universal value. The results of the author's experiments are compared with the calculations, and the value of the constant involved in the eddy kinematic viscosity is determined.
