AN EXPERIMENTAL STUDY ON FLUID FRICTION AND HEAT TRANSFER IN COMPLEX NONCIRCULAR PASSAGES
Due to the effect of centrifugal force in an operating turbine
the passage between the tenon of blade root and the mortise of the disk is formed as complex noncircular flow passage.The characteristics of flow friction and heat transfer in this kind of noncircular passages are investigated experimentally.It is discovered that the "multiple flow states" occur in the noncircular passages and some special features exist in the flow friction and heat transfer characteristics.The criteria of the flow friction and heat transfer are obtained for this case.
