TL;DR: In this article, the authors derived a correlation for the Nusselt number of the form suggested by this evidence using a selection of the data and showed that this exponent should be a function of nozzle-to-plate spacing and of the radial displacement from the stagnation point.

TL;DR: In this article, the authors analyzed the acoustic perturbations from a supercritical nozzle of finite length, in which the velocity increases linearly through the nozzle, for several inlet and discharge Mach number values and over a wide frequency range.

TL;DR: In this paper, the appearance of additional vortices for curved pipes of particular cross-sectional forms, existence of dual solutions, and effects of the pitch on the flow in a helically coiled pipe are presented.
Abstract: This paper brings together recent information on flow in curved pipes. As to fully developed laminar flow, the appearance of additional vortices for curved pipes of particular cross-sectional forms, existence of dual solutions, and effects of the pitch on the flow in a helically coiled pipe are presented. In the case of developing laminar flow in a curved pipe, fascinating behavior of the separation of the secondary flow boundary layer near the inner wall is shown. Flow in a rotating curved pipe and a periodically curved pipe are also discussed. Different hydrodynamic conditions at the inlet greatly affect the flow in the bend ; a strong swirl is created downstream of two 90° bends in combination according to the combination angles. A brief description of the discharge coefficients for bend flowmeters, and unsteady flow in curved pipes are also given.

TL;DR: In this article, an attempt has been made to form a qualitative correlation between the nozzle shape and the issuing jet shape, which is best achieved by a sudden, smooth contraction of the flow area from the supply line to the desired nozzle diameter.
