| Research Abstract |
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.
