Very Important* How to Find the Drag Coefficient of L Angle 50x50x500mm

Question asked by Naga Gopal on Jun 20, 2019

when I was trying to Comparing with the standard value, the achieved value was completely wrong. so please check the model with the given data below and let me know how to resolve this ?

 

Size: L angle 50x50x500mm.

Wind Velocity in X Direction = 47M/S  (0 deg)

 

 

Computational Domain Size:

                   X,     -X

   Y,   -Y

    Z,    -Z

Study A   0.625, -0.625

0.5, -0.5m

0.625, -0.625 m

Goals: 

 (Based on equation) 

Applied Equation:

({SG Force (X) 1} *2)/ (1.2*47^2) *(0.05*0.5)

({GG Force (X) 1} *2)/ (1.2*47^2) *(0.05*0.5)

 

Standard Values: ( Cf – 1.8  Required Standard Value   )
