We have constructed a numerical simulation model for Si nanoparticle synthesis using the Tandem Pulse Modulated Induction Thermal Plasma (Tandem-PMITP) and Time-Controlled Feeding of Feedstock (TCFF) method. In this model, electromagnetic thermal-fluid simulation for Tandem-PMITP is combined with the calculation of the behavior of feedstock particles, as well as the nucleation and growth of nanoparticles. In this paper, we investigated the effect of modulating the coil current cycle on the number and size of synthesized nanoparticles using this model.
