Research of Flow and Pressure Pulsation in Aircraft Deicing System

摘要

Aiming at the flow and pressure pulsation caused by the reciprocating pump in aircraft deicing system, two solutions are presented in the paper. First, based on computational fluid dynamics and finite element analysis theory, the assembled ways of rigid and flexible accumulators are applied to absorb vibration in order to inhibit the pulse. Then, the control algorithm for multiple phases of three pumps is used to offset the pulse energy among the pumps. At last, simulation results show that both methods have effectively reduced the pulsation in the aircraft deicing system.
