A Study on the Wall Heat Loss from Diesel Spray Flame (Fourth Report)
ディーゼル噴霧火炎における壁面熱損失に関する研究(第4報)
Diesel engines have a high thermal efficiency, but 20-30% of the input heat quantity is lost as the cooling loss. It is important to investigate the mechanism of wall heat transfer with impinging flame on the wall in improving the thermal efficiency. Therefore, in order to investigate the correlation of diesel flame and the wall heat loss, chemiluminescence photography, luminous flame photography and measurement of heat flux were carried out by using a wall insertion type constant volume vessel.ディーゼル機関は高い熱効率を有しているが，投入熱量の20～30％が冷却損失として失われており，熱効率を向上させる上で壁面熱伝達メカニズムの解明は重要である．そこで壁面挿入型定容燃焼容器を用いて火炎直接撮影および熱流束測定を行なうことでディーゼル火炎と壁面熱損失の相関性を調査した．
