- 論文の詳細を見る
Simple approximate equations were obtained with high accuracy for the periodic steady outlet water temperature amplitude and the efficiency of flat plate solar collectors which were subjected to a comparatively short period of incident solar energy fluctuation. These equations were based on Taylor's expansion, concerning eleven non-dimensional parameters which composed the basic equations shown in the first report, around a typical flat plate solar collector specifications. Furthermore, considering the effects of each parameter, those approximate equations were simplified. In an ordinary case, the above two quantities could be obtained easily by summing about ten terms, respectively, with sufficient accuracies.
