Benefits of SiMusCP, a musculoskeletal modelling decision making procedure, on hamstring lengthening outcomes: a retrospective study

Abstract

This work aims to establish an empirical correlation for predicting the heat transfer enhancement of planar elastic tube bundle by flow-induced vibration in the Reynolds number range of 100–600. The effects of tube wall thickness, tube pitch and tube row spacing on the heat transfer enhancement were investigated using a two-way fluid structure interaction calculation. Results demonstrated that the vibrational Reynolds number played a dominant role in heat transfer compared to the Reynolds number. The value of the heat transfer enhancement decreased with the increase of tube wall thickness, up to 43.4% in the range of 0.75–1.5 mm, and increased with the increase of tube pitch, up to 101.4% in the range of 20–30 mm. It was observed that the heat transfer enhancement was more sensitive to the change in the tube pitch. The value of the heat transfer enhancement increased with the tube row spacing in the range of 40–60 mm and kept almost stable in the range of 60–70 mm. It was denoted that the maximum critical value of the tube row spacing was enlarged to 6D owing to the flow-induced vibration. At last, an empirical correlation was obtained for predicting the heat transfer enhancement of planar elastic tube bundle by flow-induced vibration, which integrated the effects of the vibrational Reynolds number and Reynolds number.
