AI Technical Summary
Existing technologies struggle to effectively simulate and calculate the hydraulic characteristics of support plates in the bend sections of shell-and-tube heat exchangers. In particular, the differences in hole shape and size among different support plate structures make it difficult to calculate resistance and pressure drop. Furthermore, the inclined structure of the prototype support plate lacks an effective equivalent alternative, making it difficult to obtain hydraulic characteristic data.
Design a stacked pipe support plate hydraulic characteristic test device, including an inlet section, a test section and an outlet section. The test section is equipped with multiple layers of support plates and pressure tapping holes. The support bars in the support plates are distributed radially in a stepped manner. The pressure drop is measured by a pressure measuring component to establish the relationship between the local resistance coefficient and the Reynolds number, thereby realizing the equivalent simulation of the prototype bend section.
It provides a reliable physical model to ensure that fluid disturbances and velocity distribution are equivalent to actual bends in the pipe, accurately measures the pressure drop of the support plate, reduces assembly deviations and flow channel deformation, provides reliable resistance characteristic data, and supports heat exchanger design.
