In order to make the simplest flow field of opposed jets, two circular pipes having the same geometrical dimensions were employed. Factors influencing the position of the impinging surface were experimentally studied by means of a rotary hot-wire anemometer. As a result, it was found that the position of the impinging surface was mainly decided by the pressure-diffusion term of the well known turbulent energy equation ; and a peculiar phenomenon on the center line velocity field was found.
