A fan assembly includes an annular nozzle and a system for creating a primary air flow. The nozzle includes an outer wall and an inner wall surrounded by the outer wall, the inner wall defining a bore having a bore axis. The nozzle also includes an interior passage located between the inner and outer walls, and extending about the bore axis for receiving an air flow, and an air outlet located at or towards the front of the nozzle for emitting the air flow. The nozzle is configured to emit the air flow through the air outlet in a direction extending away from the bore axis.

1. An annular nozzle for a fan assembly, the nozzle comprising: an outer wall and an inner wall surrounded by the outer wall, the inner wall defining a bore having a bore axis and having a cross-sectional profile in a plane containing the bore axis which is in a shape of part of a surface of an airfoil, wherein the airfoil has a leading edge, a trailing edge, and a chord line extending between the leading edge and the trailing edge, wherein the chord line extends in a direction from the leading edge to the trailing edge towards the bore axis;an air outlet located at or towards the trailing edge of the airfoil for emitting an air flow; andan interior passage located between the inner and outer walls, and extending about the bore axis for receiving the air flow, wherein the interior passage comprises an air channel that extends towards the air outlet in a direction extending away from the chord line such that the air flow emitted from the air outlet is in the direction extending away from the chord line and the bore axis, the extending direction of the chord line, and the extending direction of the air channel are nonparallel. 2. The nozzle of claim 1, wherein the inner wall comprises a front section and a rear section, and wherein the front section of the inner wall has a shape which is substantially conical. 3. The nozzle of claim 2, wherein an angle of inclination of the front section of the inner wall to the bore axis is between 0 and 45°. 4. The nozzle of claim 1, wherein the airfoil has the shape of a NACA airfoil. 5. The nozzle of claim 1, wherein an angle subtended between the bore axis and the direction in which the air flow is emitted from through the air outlet is between 0 and 45°. 6. The nozzle of claim 1, wherein the air outlet extends about the bore axis. 7. The nozzle of claim 6, wherein the air outlet is generally annular in shape. 8. The nozzle of claim 1, wherein the air channel is inclined to the bore axis. 9. The nozzle of claim 1, wherein the air channel has a shape which is convergent. 10. The nozzle of claim 1, wherein an angle subtended between the air channel and the bore axis is in the range from 0 to 45°. 11. The nozzle of claim 1, wherein a majority of the inner wall tapers towards the bore axis. 12. The nozzle of claim 1, wherein the angle subtended between the bore axis and the direction in which the air flow is emitted from the air outlet is substantially constant about the bore axis. 13. The nozzle of claim 1, wherein the angle subtended between the bore axis and the direction in which the air flow is emitted from the air outlet varies about the bore axis. 14. The nozzle of claim 13, wherein the angle subtended between the bore axis and the direction in which the air flow is emitted from the air outlet varies about the bore axis between at least one maximum value and at least one minimum value. 15. The nozzle of claim 13, wherein the angle subtended between the bore axis and the direction in which the air flow is emitted from the air outlet varies about the bore axis between a plurality of maximum values and a plurality of minimum values. 16. The nozzle of claim 15, wherein the maximum values and the minimum values are regularly spaced about the bore axis. 17. The nozzle of claim 15, wherein the angle is at a minimum value at or towards at least one of an upper extremity and a lower extremity of the nozzle. 18. A fan assembly comprising a system for creating an air flow and the nozzle of claim 1 for emitting the air flow. 19. A fan assembly comprising a system for creating a primary air flow and an annular nozzle comprising: an outer wall and an inner wall surrounded by the outer wall, the inner wall defining a bore having a bore axis and having a cross-sectional profile in a plane containing the bore axis which is in a shape of part of a surface of an airfoil, wherein the airfoil has a leading edge, a trailing edge, and a chord line extending between the leading edge and the trailing edge, wherein the chord line extends in a direction from the leading edge to the trailing edge towards the bore axis;an air outlet located at or towards the trailing edge of the airfoil for emitting the air flow; andan interior passage located between the inner and outer walls, and extending about the bore axis for receiving the air flow, wherein the interior passage comprises an air channel that extends towards the air outlet in a direction extending away from the chord line such that the air flow emitted from the air outlet is in the direction extending away from the chord line and the bore axis, the extending direction of the chord line, and the extending direction of the air channel are nonparallel.
