“…The correlations for the heat transfer coefficient and the pressure drop proper of each MF geometry have been derived with the CtFD periodic modeling, as in [3]. Typically these quantities are arranged in terms of dimensionless number (the Nusselt number and the friction factor , respectively) and correlated to the flow conditions, which are described by the Reynolds number (also dimensionless).…”

“…This strategy has been validated on short samples (so called mock up) of a MF HX [1], whereas the correlations derived for the W7-X 18.2 kA current lead prototype MF HX, once implemented in the 1-D code CURLEAD [2], were able to reproduce precisely the experimental temperature profiles along the CL and the pressure drop inside the MF HX [3].…”

In this paper we extend the recently developed CtFD strategy for the analysis of the thermal-hydraulics of a meander flow type heat exchanger, validated against the Wendelstein7-X (W7-X) High Temperature Superconductor (HTS) current lead prototype experiment, to the case of a heat exchanger for a 68 kA HTS current lead. We aim to assess the optimized operative conditions and the influence of different geometrical configurations on the performance of the heat exchanger.Index Terms-Fin type heat exchanger, fusion magnets, high temperature superconductor current lead.

“…Compared with the traditional multi-block grid structure, it can simulate the flow field of more complex geometry, and with the characteristics of the grid more adapt to the flow. In this paper, numerical experiments on density jump in a long corridor were carried out again using the CFD software STAR-CCM+, which is widely used to study heat loss (Miettinen, 2011), heat exchange (Rizzo et al, 2011) and fuel oil combustion (Goldsworthy, 2006). As STAR-CCM+ enjoys advantages in parallel computing of fire simulations, the software was used for simulating density jump.…”
