Abstract

The invention relates to a mixing device which is arranged in a flow channel and a mixing method for mixing a fluid flowing through the flow channel in a main direction of flow. The mixing device has a plurality of mixer disks which generate leading edge eddies in a fluid flowing through the flow channel in a main direction of flow. The mixer disks are arranged in mixer disk rows in row axes running essentially across the main direction of flow. The mixer disk rows are arranged side by side in the main direction of flow in a common flow channel section where the mixer disks of neighboring mixer disk rows are alternately angled in a positive angle of attack and in a negative angle of attack with respect to the main direction of flow.According to this process, the fluid flowing through the flow channel is mixed thoroughly by a leading edge eddy system, whereby in the mixing method presented here at least two contra-rotating leading edge eddy systems are generated in a common flow channel section.
