Systems for mixing gaseous medium streams at different temperatures are for changing the direction of flow of a stream which alleviate the effect of pressure losses. A plurality of hollow airfoil shaped vanes are positioned within a first gaseous stream, and the second stream is conveyed through the hollow vane and discharged into the first stream through a slot at the trailing edge of the vane. Fixed or movable flow direct the rate and direction of the discharge flow.
