This paper aims at establishing a generalized method for predicting wear due to solid-gas flow through a duct. It has been opined that not only does the duct wear out, the particles carried through the duct themselves degrade in the process. The correct evaluation of the fluid-particle, particle-duct and fluid-duct interactions forms the basis of the theoretical equation proposed for the purpose. The method proposed is verified by conducting experiments on a well-designed set-up. The test rig helped to evaluate the essential parameters responsible for the wear such as the material, duct and fluid interaction parameters. As a test case, a 90° bend placed in a vertical plane carrying material from bottom to top has been considered.
