摘要:
为研究驻波压力场速度波腹位置射流的雾化特性,基于八叉树结构形式的网格自适应方法与多尺度仿真算法构建了射流雾化的数值模拟方案,通过在计算域边界施加扰动构建了一阶横向驻波压力场。在此基础上实现了振荡压力场与雾化的多物理场耦合计算,研究了驻波压力场速度波腹位置射流雾化的响应特性,基于气体动力学理论阐述了速度波腹位置射流雾化的响应机理。结果表明:基于自适应网格与多尺度仿真算法建立的雾化数值模拟方案可以实现雾化过程较为准确的求解,是研究雾化过程的有力工具; 反压振荡与雾化的耦合求解算法可以研究振荡压力场下的雾化特性,对于进一步认识非定常雾化特性并揭示热声耦合机理起到重要的作用; 射流处于速度波腹位置时,圆柱射流发生变形变成扁平液膜,并伴随气流的运动发生周期性摆动,破碎长度减小,破碎程度加剧。
Abstract:
To investigate the characteristics of liquid jet atomization in the standing wave pressure field, a numerical scheme of liquid jet atomization was established based on octree adaptive mesh refinement and multiscale algorithm. A first-order transverse standing wave pressure field was established by exerting perturbations at the boundary of the computational zone. On this basis of the above methods, the multi-physical coupling simulation of pressure oscillation and atomization was carried out. The response characteristics of liquid jet atomization on velocity antinode position at the standing wave pressure field was studied. The response mechanism of liquid jet atomization was interpreted based on gas dynamics theory. The results reveal that the atomization process can be accurately solved by the established numerical scheme based on adaptive mesh refinement and multiscale algorithm, and it is a powerful tool to investigate the atomization process. The atomization characteristics coupled with pressure oscillations can be studied based on the coupled simulation algorithm between pressure oscillations and atomization. It will play an important role to further investigate the unsteady atomization process and the mechanism of thermo-acoustic positive feedback. When the jet is in the position of the velocity antinode, the liquid column jet is flattened to liquid sheet, acompanied by the periotic swing of liquid jet with the gas flow. The breakup length is shortened, and the breakup degree is enhanced.
