This approach can be used for unsymmetrical fuselage if one able to provide the angle of attack at zero lift for the corresponding fuselage as it had been done by Wolowicz C.H and Yancey R.B [2], Another method for predicting the fuselage’s aerodynamics characteristics may use CFD approach as it had been done by Lee [3] for the case of fuselage’s helicopter.

Established Numerical Simulation Model.
Numerical simulation conforms to real simulation results.

For this reason, the use of numerical simulations becomes more interesting [8].
Particle tracing In many scientific areas as well as in technical applications, finite element simulation is of central importance.
In Computational Fluid Dynamics (CFD) time dependent and time independent velocity fields are differentiated.
This operation has to be evaluated at the beginning of the particle tracing simulation as well as in every flow line generation loop.

The calculation method Based on the CFD software FLUENT, the density base solver was used, the implicit control equations form was selected.
The example and application of FLUENT simulation calculation.

Mostofa[3] showed that the vortex created inside the mixing chamber by CFD simulation.

While there are advantages to the OHAD system, the obtained CFD findings demonstrated that the UFAD system may outperform it.
The computational fluid dynamics (CFD) findings validated that, in comparison to the OHAD system's 1.2 m height, the UFAD system could keep the room temperature at 26°C while being located below 2.0 m.
