Due to the importance of studying the flow pattern around ARs of different shapes such as cubes, pyramids and triangular prisms, many studies have been conducted experimentally in wind tunnel, using Computational Fluid Dynamics (CFD) simulations to study the effect of geometry of these ARs on the flow pattern around them [15]-[16].
The results were then used to verify the numerical results obtained from finite volume method (FVM) simulations [17].

Theory and Simulation Research.
In recent years, with the rapid development of the CFD software, such as FLENT, CFX more and more EAHE models and simulation studies have been proposed.
In 2002, Jiang Qing et al. [33] conducted a three-dimensional transient simulation of the EAHE by using FLUENT 5.4.
These cause the inaccuracy of the simulation results.
