Abstract: Disclosed is a wind turbine blade having a blade de-icing system. The blade de-icing system comprises: a first channel longitudinally extending from a first position to a second position, wherein the second position is between the tip end and the first position; and a heating channel longitudinally extending from the second position to the first position along the leading edge of the wind turbine blade, the heating channel and the first channel being in fluid connection. The blade de-icing system is arranged to provide a flow of heated fluid through the first channel and the heating channel, the flow of heated fluid through the heating channel having a main flow direction along a longitudinal direction of the wind turbine blade, and wherein the blade de-icing system is configured to affect the flow of heated fluid through the heating channel resulting in a rotational flow of the heated fluid about the main flow direction.
