Abstract

This study investigates the numerical simulation of the internal flow field in  double helical gear-driven viscous dampers. It outlines the working principles and struc- tural characteristics of the damper, highlighting its potential in seismic mitigation for architectural structures. Numerical simulations were performed using computational fluid  dynamics software (FLUENT), revealing prominent characteristics of the internal flow field. By analyzing the flow field properties under various conditions, optimization strategies  were proposed for designing novel viscous dampers and determining optimal parameters. This research offers theoretical support for the design and application of double helical  gear-driven viscous dampers, while providing valuable insights into numerical simulation  studies of complex flow phenomena.
