Aerodynamic Characteristics of Radar Antenna in Stationary and Azimuthal Rotational Motion

Table 2

CFD mesh-independence verification for V = 28 m/s with K = 0.11. Data in parentheses are the percentage differences in aerodynamic coefficient values between the current number and the finest mesh number (solid plate antenna).

Mesh number	16 million	8 million	4 million
Cx	2.33	2.34 (0.4%)	2.33 (0%)
Cz	−1.24	−1.23 (0.8%)	−1.25 (−0.8%)
Cmx	−0.87	−0.87 (0%)	−0.87 (0%)
Cmy	0.11	0.11 (0%)	0.10 (−9%)
Cmz	1.53	1.54 (0.7%)	1.54 (0.7%)
