ABSTRAKT

Synthesis of single-walled carbon nanotubes (SWNTs) based on the evaporation of carbon-containing raw materials and metallic catalysts by using a radio frequency (RF) induction plasma is explained. The high temperature region inside plasma evaporates the materials. Then, homogeneous condensation of the metallic catalyst provides nucleation sites for initiation and growth of carbon nanotubes. Computational fluid dynamics (CFD) modeling is used to study the thermal flow and particle evaporation inside the entire region of induction plasma. Flow field coupled with the electromagnetic field equations inside the plasma region were solved, and the injected particles were tracked. The evaporation of particles inside plasma was investigated, and the nucleation of nickel nanoparticles (metallic catalyst) inside the reactor was simulated by the discrete sectional method. Eventually, the growth of carbon nanotubes on the nickel particles was estimated.
