Development of Atmospheric Intermediate-Temperature Plasma Flow System for Synthesis of Biocompatible Nanomaterials

从化学工程和流体力学的角度出发，对等离子体反应热流体场合成生物相容性纳米材料的基本过程进行了实验、理论和数值研究。因此，集体生长和对流/扩散传输的纳米粒子和大气等离子体流的湍流行为的同时进行的过程被澄清。此外，流体动力学不稳定性的动态分离，边界层的局部外部扰动和条纹结构和射流之间的相互作用的感受性被揭示。此外，还证明了SPH方法适用于等离子体流中悬浮液的破碎过程。

From the viewpoints of chemical engineering and fluid mechanics, experimental, theoretical and numerical studies were carried out to investigate the fundamental processes that are involved in the biocompatible nanomaterial synthesis using a reactive thermofluid field of plasma. In consequence, the simultaneous processes of the collective growth and convective/diffusive transports of nanoparticles and the turbulent behavior of an atmospheric plasma flow were clarified. Furthermore, fluid-dynamic instabilities on dynamic separation, boundary layer receptivity for local external disturbance and interaction between a streaky structure and a jet flow were revealed. In addition, it was demonstrated that SPH method was applicable to the breakup process of precursory solution in a plasma flow.
