Static Strength Assessment of the Water Vapor Cyclone
Figure 1. 3D CAD model of the water vapor cyclone: a) shade; b) transparent view
Subject of the investigation was determination of a static strength and utilization factors of the water vapor cyclone (WVC), which is shown on the Figure 1.
To check strength and deformation of issued design finite element model (FEM) was done (Figure 2).

WVC normally operates under the following conditions:
Mentioned initial conditions were applied to FEM as shown in Figure 3.
Operational conditions, including pressure pulsating loads, have been determined from CFD calculation report. Pressure distribution and pulsating in low frequency domain are shown in Figures 4 and 5.

After checking of FEM analysis results and verified with analytical solutions the following conclusions have been made:
Von Mises Stress distribution level and axial translation in WVC can be seen in Figures 6 and 7.
