Highlights

• A 90° elbow equipped with guide vane was developed to reduce elbow erosion.

• Response R₁ shows a quadratic perturbation with the change of structure factors.

• Response R₂ has a linear relationship with the selected structure factors.

• The optimal geometry was obtained by using a desirability function approach.

• The modified elbow has a larger low-speed region and a lower DPM concentration.

Abstract

A 90° elbow equipped with guide vanes was developed with the intent of reducing elbow erosion. Numerical models were formed to predict the maximum erosion rate of elbow and Face-1, and the response surface methodology was used to study the relationship between the erosion rate and structural parameters of guide vane. A second-order response surface model was established to determine the relationship between R1 and variables, and a reduced cubic (RC) polynomial model was obtained to reveal the relationship between R2 and the three factors. The numerical results show that the low-speed region is expended and the maximum discrete particle matter (DPM) concentration is reduced after installing the guide vane. This internal component provides a shelter for the elbow from the direct impact of high-speed solids.
