Summary This paper presents an experimental study on the behaviour of bluff turbulent surface jets discharged into a stagnant ambient for moderate and large source Richardson numbers. Based on fairly extensive observations, the velocity and temperature profiles in the Lateral and vertical directions have been found to be similar. Using the results of an earlier theoretical analysis (by the authors) and the present experimental results, the variation of the velocity, temperature excess and length scales have been correlated with the nondimensional longitudinal distance from the outlet (made dimensionless with the square root of the surface jet at source), and the source Richardson number.
