It is well known that the Taylor-Goertler vortex arises when a two-dimensional jet flows on the concave surface of circular cylinder of
y0.5/
R≥0.17-0.27 (
y0.5: half width of jet,
R: radius of cylinder). Many researches have done to clarify the condition to arise the Taylor-Goertler vortex, the profile and the stability of the vortex and so on. But, the analysis for the decay of the maximum velocity and the pressure distribution in the flow field have not been clarified yet. This study shows the equation of velocity profile and clarifies the flow characteristics (decay of the maximum velocity, pressure distribution in the flow field and so on) under that the Taylor-Goertler vortex does not arise (
y0.5/
R≤0.17-0.27) using the momentum integral equation and its validity is confirmed by the experimental results.
