Corner Losses in Ducts: Factors Affecting the Design of Efficient Corners and Leading to Reduction of Resistance

Abstract

DUCT systems of various types are used on aircraft. The efficiency of the systems depends upon the losses in the duct. A corner in the duct may produce a large resistance to flow if it is not carefully designed. Research on the problem of corner resistance has been undertaken by a number of investigators. Their results show that the design of a corner is very important. In the following discussion the more significant results are summarized and some factors governing the design of an efficient corner are set forth.
