    Abstract: In this paper, a discussion of results is presented for the dimensionless analysis of generating irreversibility of vessels in which mixing and heating of fluid are done simultaneously. In the first case, the impeller inside the mixing vessel is the heating body, and in the second case heating body is a fixed ring and the impeller inside the vessel... Show More

    Abstract: In this paper the ratchetting behavior of four pairs of stainless steel, long and short radius welding elbows is studied under conditions of steady internal pressure and in-plane, resonant dynamic moments that simulated seismic excitations. The finite element analysis with the nonlinear kinematic hardening model has been used to evaluate ratchettin... Show More
