All computations have been performed using a customized version of the CFD commercial code FLUENT©.
The main advantage of LES is that the entrainment of every single cold eddy can be taken into account in the simulation, so allowing the calculation of particle trajectories using non-average flow and temperature fields.
Two sets of simulations have been carried out at 3 MHz and 13.56 MHz, respectively, with different powder feed rates.

Variable fidelity optimization (VFO) is a recently developed method to solve computationally expensive problem in simulation-based design [3].
There has several kind of variable fidelity model sources: (1) different physical or mathematical description, such as Navier-Stokes viscous Newton equation and Euler non-cohesive equation (2) different resolution, such as coarse and refined finite element grid (3) different precision, such as simplified boundary conditions, the 2 d model instead of 3 d model(4) different experiment method, such as wind tunnel test, CFD finite element simulation and engineering experience estimate and so on.
But in the variable fidelity modeling, the samples derived from multilevel fidelity simulations.
However, the variable-fidelity modeling approach only used 15 high-fidelity simulations while the high fidelity approximation needed 30.
