Abstract
In the paper named "Forecasting the Length of the Undeveloped Flow Region in the Inlet of Asymmetric Bifurcations I", also presented to this congress, an equation of prediction of the length of the not fully developed flow region in asymmetric bifurcations is proposed. However, only the variation of the bifurcation angles and flow rates, for a pipe with 20 mm in diameter, are evaluated. In this work, it is intended to complement this first manuscript with results acquired from simulations where the diameter of the tube is varied. Constants and exponents are calculated from the measurement of the region of interest in the images generated via CFD. Thus, a more complete equation is obtained, with values collected from the variation of all the quantities that influence the phenomenon. The development of a prediction equation for the thermal entrance length, in a method similar to the present one, is recommended to complete the study of the entrance region in bifurcations.
