To the best of our knowledge, only few researchers have made attempts to minimize the erosion in bends by modifying the bend configuration in order to alter the particle-laden flow pattern to reduce the erosion. In this work, we revisited those previously proposed bend configurations to reduce erosion, in additional to two of our own design. We found that secondary flows play an important role on the erosion pattern (impact location and impact angle). The secondary flows depend on the pipe configuration. More work has to be done in this direction. We might be able to minimize erosion with bend configuration. However, this also depends on particle and fluid characteristics. In the near future, we will also include erosion in our models.
