The investigation of spray flame synthesis of nanoparticles on a well-defined standard burner by experiment and simulation is the central idea of the SPP. For this purpose, a burner was constructed that combines a geometry suitable for experiment and simulation with good optical access and simple boundary conditions, thus enabling a close exchange between experiment and simulation - for a deeper understanding of the process but also for mutual validation of the calculation and measurement methods. This burner was manufactured several times and made available to all relevant groups of the SPP, operating conditions were defined and procedures for quality assurance were established. The burner is now to be developed systematically, further interesting standard operating conditions are to be established, and problems for measurement and simulation are to be solved, e.g., by reducing the occurring flame pulsation. For these burner developments, methods for the measurement of spray properties, gas-phase velocities, and chemiluminescence are used, partly also with high speed diagnostics. The applicants have a laboratory with permanently installed burners and corresponding diagnostics; this laboratory is also made available to other project partners. This will allow joint measurement campaigns to generate simultaneous data sets with complementary measurement techniques.In addition to the standard experiment, the present central project is also developing a total simulation, in which submodels and materials properties from the various subprojects of the SPP are to be integrated in order to test the influence of these models on a stable standard configuration. At the same time, this standard simulation also allows to evaluate planned modifications of the burner in a relatively uncomplicated way. Finally, a database was implemented by the central project to document, comment and archive essential results of the entire SPP. The content and functionality of the database is to be further expanded, and the quality of the data sets contained and their documentation is to be constantly improved by a curator. With this database, the central project brings together the knowledge gained in the SPP and makes the results available in a scope that goes far beyond classical publications. Ultimately, this database is to be established as a standard and reference, backed by a comprehensive data set, which will have an impact far beyond the duration and partners of the SPP and thus promote the research and development of spray flame based nanoparticle synthesis in the long term.

SPP的核心思想是通过实验和模拟研究在标准燃烧器上喷射火焰合成纳米颗粒。为此，我们设计了一种燃烧器，其几何形状适合于实验和模拟，具有良好的光学通道和简单的边界条件，从而实现了实验和模拟之间的密切交流-不仅可以更深入地了解工艺，还可以相互验证计算和测量方法。该燃烧器经过多次制造，并提供给最高人民检察院的所有相关团体，规定了操作条件，并建立了质量保证程序。现在，燃烧器将被系统地开发，将建立进一步的感兴趣的标准操作条件，并且将解决测量和模拟的问题，例如，通过减少出现的火焰脉动。对于这些燃烧器的发展，用于测量喷雾特性，气相速度和化学发光的方法被使用，部分还具有高速诊断。申请人有一个实验室，永久安装燃烧器和相应的诊断;该实验室也可供其他项目合作伙伴使用。这将使联合测量活动产生同步的数据集与互补的测量技术。除了标准的实验，目前的中心项目也正在开发一个总的模拟，其中的子模型和材料属性的各个子项目的SPP将被整合，以测试这些模型的影响稳定的标准配置。同时，该标准模拟还允许以相对简单的方式评估燃烧器的计划修改。最后，中央项目建立了一个数据库，以记录、评论和存档整个最高人民检察院的基本成果。数据库的内容和功能将进一步扩大，所载数据集及其文件的质量将由一名管理员不断改进。有了这个数据库，中心项目汇集了在SPP中获得的知识，并在远远超出传统出版物的范围内提供结果。最终，该数据库将被建立为标准和参考，并得到全面数据集的支持，其影响将远远超出SPP的持续时间和合作伙伴，从而促进基于喷雾火焰的纳米颗粒合成的长期研究和开发。
