Market requests for higher performance fans and legal requirements to meet minimum efficiency grades drive industrial fan designers to study or re-think stall control solutions. In tunnel and metro fans this means to study how anti-stall rings work and to provide strategy to improve their efficiency. Here we present a numerical study validated against available experiments on the fitting of an anti-stall ring on an axial fan for tunnel and metro operations. The study synthetize the effects of the anti-stall ring with an actuator disk, strongly reducing the computational load required and validating a new methodology. Such approach can be implemented to easily derive fan performance with different geometries of the anti-stall ring plenum as well as its fins.

Abstract

Market requests for higher performance fans and legal requirements to meet minimum efficiency grades drive industrial fan designers to study or re-think stall control solutions. In tunnel and metro fans this means to study how anti-stall rings work and to provide strategy to improve their efficiency. Here we present a numerical study validated against available experiments on the fitting of an anti-stall ring on an axial fan for tunnel and metro operations. The study synthetize the effects of the anti-stall ring with an actuator disk, strongly reducing the computational load required and validating a new methodology. Such approach can be implemented to easily derive fan performance with different geometries of the anti-stall ring plenum as well as its fins.
