A duct arrangement 100, (110, figure 5) for influencing fluid flow, comprising a first duct section 1000, (1100) receiving a fluid flow therethrough, defining a first direction 1006 through the first duct section from a fluid inlet end 1002 to a fluid outlet end 1004, a second duct section 2000, (2100) defining a second direction 2006 through the second duct section from a fluid inlet end 2002 to a fluid outlet end 2004, the second duct section comprising a vortex generator surface 3000, (3100) inducing vortices in the fluid flow through the first duct section. The vortex generator surface may be a ring comprising a series of projections 3002, (3102), e.g. serrations and/or undulations. A plurality of spatially separated vortices, e.g. periodic vortices may be generated. An aircraft or watercraft comprising the duct arrangement is disclosed. Controller (112) may control actuators (1004) to extend or retract to implement selective configuration of a vortex generator surface (3100).
