The heating of a turbulent water jet discharged vertically into a steam environment (Q1116794)

Available experimental results for the heating of turbulent water jets discharged downward into a steam environment are reviewed in terms of the Kutateladze theory for such a system. That theory defines an eddy diffusivity for heat that is proportional to the local jet Reynolds number, \(\epsilon_ H/\nu =E(ur_ 1/\nu)\), and the factor E is evaluated for the experimental results. The large range in the values of E so obtained remains essentially unexplainable and the design problem of specifying the heating of the water jet remains unresolved despite the very substantial experimental effort that has been devoted to this problem.
