“…Considerations on the wall heat transfer and on the pressure losses for a real bend, based on the flow field obtained through time-resolved particle image velocimetry (PIV) measurements, can be found in the work of Yu et al. 9 An analysis of the heat transfer is indeed of fundamental importance for the cooling system and different works studied the improvement of thermal characteristics through design modifications. 10–14 Nevertheless, the present study focuses only on the flow field characteristics, in agreement with the study of Verstraete et al.…”

The correct prediction of the flow field is of crucial importance to drive numerical optimization to a real improvement of a design. For this purpose, different numerical approaches can be used to study the fluid dynamics characteristics and the performance of the design. In particular, in the present work the Reynolds-averaged Navier–Stokes and large eddy simulation approach are compared for an internal aerodynamic application. The obtained solutions are validated against experiments through a quantitative and qualitative comparison, i.e. pressure measurements and particle image velocimetry flow visualizations, respectively.
