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.
(1) Numerical and CFD simulation are the effective ways to research the greenhouse EAHE.

Simulations were carried out on the rectangular wing model with and without winglet at aspect ratio of 2.73 and Reynolds number of 0.16 x 10 6 for various angles of attack.
The main objective of this study is to numerically perform a CFD analysis on wing without winglet and wing with semi-circular winglet at various cant angle.
The simulation was carried out at various angles of attack (α) and Re number of 0.16 x 10 6 (20 m/s).
Once the simulation of wing without winglet was done, a second simulations of wing with winglets were performed.
