Webb10 feb. 2024 · Pressure losses of combinations of bends without vanes were higher or lower than the sum of the single pressure losses of the components (combination effect), depending on the components and orientation. For bends with abrupt deflections, strong combination effects occurred; in some cases, pressure losses doubled.
