Fig. 2 Quadcopter assembly
Fig. 3 Computational domain and the mesh around the quadcopter
the mesh quality is good enough to produce accurate results as shown in Fig. 4. A
total of 1,988,470 tetrahedral elements are generated in the computational grid. For
attaining convergence in solution, each simulation took about 1000 iterations.
3.2 Hovering Phase
Quadcopter attains the hovering phase when over-all thrust matches with the downward force (gravitational weight). Hence in the hovering phase, each rotor will be
provided with the same rpm to attain stability at a certain height. In hovering phase
simulations, two parallel faces that are in the YZ plane (see Fig. 3) are given “opening”
