    Abstract

    Recently, Lee et al. (Arch Appl Mech 81:397-402, 2011) proposed a new and very interesting formula to describe the velocity profile of a submerged jet flow by introducing a radial adjusting coefficient depending on the jet flow direction. Under some simplifying assumptions (granting convergence), the authors were able to express the spreading width of the jet flow analytically in terms of infinite series. In this short note, we show that such simplifying assumptions can be relaxed and exact solutions for the spreading width of the jet flow can be obtained: Such results are computationally more efficient and are able to better demonstrate the qualitative features of the solutions.
