In this paper, the frozen rate of a rectangle container full of mackerel fish in a freezer is studied. The gap between the container and ground of freezer was varied to measure the flow and thermal fields. In addition, aluminum bars are placed into the middle portion of the container to increase the frozen rate. Both experimental and theoretical works have been conducted. A software I-DEAS is applied to simulate the air circulation in the freezer.
It is found that the calculations agree well with the data from experiments in the cases by varying thickness of the gap, which results in increasing the frozen rate. As for embedded aluminum bars inside the contained which is favorable in frozen effect in all the directions of allocation. The local hot region is effectively reduced through the highly conductive metal added. It is concluded that the performance of enhancement is more pronounced, when the axial direction of bars is in the longitudinal direction.
