Systems and methods to reduce acoustic resonance or disrupt standing wave formation in a fluid manifold of a high-pressure fracturing system

A fluid manifold for a high-pressure fracturing system, the fluid manifold comprising:

• one or more spool sections;
• a flow passage at least partially defined by the one or more spool sections that extends along a longitudinal axis;
• a first flow altering assembly positioned along the flow passage, the first flow altering assembly including a diverter surface positioned to divert fluid flowing within the flow passage radially away from the longitudinal axis;
• and
• a second flow altering assembly positioned along the flow passage and spaced from the first flow altering assembly along the longitudinal axis, the second flow altering assembly including:
• an annular flange;
• and
• a flow altering tube extending axially from the annular flange such that the annular flange and the flow altering tube define an annular cavity that extends radially between the flow altering tube and an inner wall of the flow passage and that extends axially along the flow altering tube to the annular flange,
• wherein the flow altering tube comprises an inner surface extending axially between an open upstream end of the flow altering tube and an open downstream end of the flow altering tube such that the inner surface defines a through passage extending axially through the flow altering tube,
• wherein at least one aperture having a first diameter extends radially through the flow altering tube to the through passage,
• wherein the open upstream end of the flow altering tube defines an axial opening having a second diameter greater than the first diameter.
