They can be generally classified as computational fluid dynamics (CFD) model and probability model (such as Gaussian, BM, FEM3 and etc.).
CFD models [1] are usually associated with complex parameter systems and large amount of computation, which does not apply to real-time application.
To verify the improved model, we take two groups of simulation in different aspects: final state simulation with different primary parameters, and diffusion process simulation in different time points.

The simulations were undertaken to inform on how the fluid flowed within the tube passages.
So, in the simulations, only a symmetrical half of a flow passage between the tubes is used.
The simulation was run until the residual of the pressure and velocities were less than 0.00001.
These values are chosen to best fit to the data, supported by the single-phase CFD simulations presented in this paper.
