Optimization of Nanofluid Flow and Temperature Uniformity in the Spectral Beam Splitting Module of PV/T System

The mass fraction of 0.01 wt% ZnO nanofluid was prepared via the two-step method. measurement verifies that nanofluids have better transmission characteristics in frequency division window range 400–1200 nm. At same time, it has good absorption ultraviolet and near-infrared bands, which meets application conditions spectral beam-splitting module PV/T system. A system designed. simplified physical model established ANSYS 14.0. flow field convective heat transfer were simulated for different arrangements interlayer inlet to obtain a more ideal uniform temperature distribution improve system’s comprehensive efficiency. results show fluid under case II is uniform, than other arrangements. Hence, this work could provide reference optimising within module.
