Abstract

In this article a bell mouth junction assembled in front of the test article in practice was simulated by applying ANSYS CFX, the data of relative measurement points was picked up from the simulation result and compared with test data to validate the simulation reliability. Then, aiming to dwindle in the formal diameter of a standard designed bell mouth junction to satisfy assembling inside a small-diameter pipe in front of the test article, three remodeling schemes are introduced, and the validated simulation method is applied for the three. By comparing the simulation results, the effect of bell mouth inner wall profile to its outlet flow field evenness is obtained, furthermore, the location of aerodynamic interface plane (AIP) along the axis direction of junction is confirmed, and the optimized one of the three is elected.
