  "textContent": "Methods and devices useable in turbo-engines premixing of compressed air and fuel are provided. A premixer has a mixing part configured to receive a gas flow input in a flow direction and fluid fuel injected substantially perpendicular to the flow direction. The mixing part has a rim configured to define a substantially cylindrical shape. The mixing part also has a swirler with (i) a center body located substantially in a middle of the cylindrical shape along the flow direction, and (ii) a set of vanes extending from the center body towards the rim, the vanes being configured to determine a rotation motion inside a flow that includes the received gas flow and the injected fuel when the flow passes through the mixing part, at least some of the vanes having a trailing edge with a waving profile configured to generate mixing zones inside the flow thereafter.",
