Influence of media mixing rates in T-joints upon their damage

Abstract

Mixing of media having different temperatures and velocities of separate streams often takes place in the industry. Being heated material of a pipe acquires nonuniform volume expansion as well as cyclic load, which causes pipeline lifetime decreasing. Damaged zones are to some degree dependant on the rates of mixed streams, which determine mixing process after thermo-hydraulic values are stabilized. These analyses will help to predict more effectively appearing of damaged zones.
