摘要：
Heat transfer elements (34) for rotary regenerative heat exchangers are formed with spacing ridges or notches (42) having flow-disrupted indentations (46) in the peaks of the notches (42) formed at selected intervals to project into the flow channels (36, 38). These projections (46) interrupt the boundary layer and cause turbulence and mixing to enhance the heat transfer. Various methods of forming the indentations (46) are disclosed.
