| Research Abstract |
Heat transfer experiment and pressure loss measurement have been done for the channel flow with aluminum fiber layers in order to investigate their effectiveness as an insertion device to improve the heat exchanger’s performance. It was found that the aluminum fiber layers with their axes mainly perpendicular to the wall showed quite high heat transfer performance, that is, heat transfer of twenty times as large as that of the non-insertion case was obtained. This heat transfer enhancement means one-order high value compared to the conventional fins, although much high-order large pressure loss should be paid.
