Abstract Numerical simulation are conducted to explore the characteristics of the
axial inflow and related aerodynamic noise for a large-scale adjustable fan with
the installation angle changing from −12° to 12°. In such a range the maximum
static (gauge) pressure at the inlet changes from −2280 Pa to 382 Pa, and the minimum static pressure decreases from −3389 Pa to −8000 Pa. As for the axial intermediate flow surface, one low pressure zone is located at the junction of the
suction surface and the hub, another is located at the suction surface close to
the casing position. At the outlet boundary,… More >
