| description | Abstract This article focuses on optimizing the evaporation and atomization performance of the evaporator tube in the combustion chamber of a microturbine engine, and examines its impact on engine thrust. Given that the evaporator tube design is crucial for enhancing combustion efficiency as a key component of the combustion chamber, this study introduces an innovative evaporator tube structure that incorporates biomimetic design principles through theoretical exploration. The proposed structure adds specifically sized grooves to the inner wall of traditional evaporation tubes to improve the evaporation and atomization processes of fuel droplets. The effectiveness of this design is demonstrated by comparing and analyzing the differences in evaporation and atomization characteristics between traditional and biomimetic evaporation tubes. As the incoming air temperature increases, the diameter of fuel droplets decreases, while the evaporation rate significantly rises. Moreover, when the biomimetic tube’s inner wall grooves are precisely designed with a width of 0.5 mm, a depth of 0.6 mm, and a length of 1.5 mm, the atomization effect of fuel droplets reaches its optimal state, significantly improving the evaporation rate compared to traditional evaporation tubes. |
