Abstract

PURPOSE: To reduce secondary flow loss by a blade lattice device by constituting same such that a blade has a plurality of successive grooves or ribs formed on its rear surface in a particular angular relation to a side-wall in order to inhibit development of corner vortices generated in a flow passage between adjacent blades of the device.
