This work reported the boiling test of biological aggregates, with particular attention on the correlation of aggregate structure with the boiling efficiency. The aggregates of different interior structures had been adopted for boiling tests. The aggregates with higher overall fractal dimension will have a more efficient nucleate boiling. The transient contact of the floc with the heating surface would produce tiny bubbles of size of several tens μm that markedly enhance local heat transfer rate.
本論文報告生物聚集體 (biological aggregates) 之沸騰測試，尤其著重在聚集體結構與沸騰效率間之關聯。將各種不同內部結構之聚集體進行沸騰測試，實驗顯示具有較高碎形維度 (fractal dimension) 的聚集體展現較高效率的核沸騰，膠羽 (floc) 瞬間接觸加熱板表面將產生數十微米的微小氣泡並大幅增加區域熱傳速率 (local heat transfer rate)。
