A mixer configured to provide a fuel-air mixture to a combustor of an engine, the mixer comprising: a mixer body having an outer surface, an inner wall, an interior passage, and a central axis; a fuel inlet located parallel to the central axis, the fuel inlet having a fuel passage and configured to introduce a fuel flow to the interior passage of the mixer body; a central air jet located parallel to the central axis; a first set of openings inclined with respect to the central axis; and a second set of openings having an inlet surface tangential to the mixer body, wherein the central air jet delivers, in use, a central air flow to the interior passage of the mixer body, the first set of openings introduces, in use, a first air flow to the interior passage of the mixer body, and the second set of openings introduces, in use, a second air flow to the interior passage of the mixer body, and wherein the first set of openings and the second set of openings are located circumferentially around the outer surface of the mixer body, wherein the first set of openings and the second set of openings extend through the mixer body from the outer surface to the inner wall, wherein the mixer body includes a conical surface, wherein the central air flow pulls, in use, the fuel along through the passage of the mixer, wherein the first air flow impinges, in use, on the conical surface to push fuel toward the central axis and creates, in use, an air boundary layer along the inner wall, wherein the first and second air flows and introduce, in use, a swirling flow due to the inclination of the air flow with respect to the passage, wherein the inclination of the first and second air flows and imparts, in use, a swirling flow into the mixer, wherein the first and second air flows and are introduced, in use, at such an angle such that the first and second air flows and push the fuel flow into the passage and away from the inner wall allowing for the mixture of the fuel and air to be kept away from the boundary layer, wherein the first air flow impinges, in use, on the conical surface to push the fuel toward the central axis, and wherein the second air flow stays, in use, near and/or adheres to the inner wall to create high velocity in a boundary layer to prevent fuel flow from migrating to the inner wall. a mixer body having an outer surface, an inner wall, an interior passage, and a central axis; a fuel inlet located parallel to the central axis, the fuel inlet having a fuel passage and configured to introduce a fuel flow to the interior passage of the mixer body; a central air jet located parallel to the central axis; a first set of openings inclined with respect to the central axis; and a second set of openings having an inlet surface tangential to the mixer body, wherein the central air jet delivers, in use, a central air flow to the interior passage of the mixer body, the first set of openings introduces, in use, a first air flow to the interior passage of the mixer body, and the second set of openings introduces, in use, a second air flow to the interior passage of the mixer body, and wherein the first set of openings and the second set of openings are located circumferentially around the outer surface of the mixer body, wherein the first set of openings and the second set of openings extend through the mixer body from the outer surface to the inner wall, wherein the mixer body includes a conical surface, wherein the central air flow pulls, in use, the fuel along through the passage of the mixer, wherein the first air flow impinges, in use, on the conical surface to push fuel toward the central axis and creates, in use, an air boundary layer along the inner wall, wherein the first and second air flows and introduce, in use, a swirling flow due to the inclination of the air flow with respect to the passage, wherein the inclination of the first and second air flows and imparts, in use, a swirling flow into the mixer, wherein the first and second air flows and are introduced, in use, at such an angle such that the first and second air flows and push the fuel flow into the passage and away from the inner wall allowing for the mixture of the fuel and air to be kept away from the boundary layer, wherein the first air flow impinges, in use, on the conical surface to push the fuel toward the central axis, and wherein the second air flow stays, in use, near and/or adheres to the inner wall to create high velocity in a boundary layer to prevent fuel flow from migrating to the inner wall.
