Thermal enhancement factors for 3D printed elements in square tube

Popis výsledku v původním jazyce

In this paper, the increases in heat transfer intensity in a square tube as well as the pressure losses from 3D printed elements are experimentally measured. To measure the heat transfer coefficient, we chose a dynamic, thermal oscillation method (or TOIRT method), which we validated on a well-known experiment of water flow in a pipe and compared the data with the most frequently cited Gnielinski correlation with Hausen correction. A twisted tape with different pitches was chosen as an element and its pressure loss was measured simultaneously, which we converted to a Fanning friction factor. We determined the thermal enhancemet factor by the ratio of heat transfer gain and pressure loss and found the optimal helix pitch p=0.87h.
