Unit I Power Losses in a Wind Tunnel

Power Losses in a Wind Tunnel
The total power loss in a wind tunnel may be split into the following components.

• Losses in cylindrical parts.
• Losses in guide vanes at the corner (in closed circuit tunnels).
• Losses in diffuser.
• Losses in contraction cone.
• Losses in honey comb, screens etc.
• Losses in test-section (jet losses in case of open jet).
• Losses in exit in case of open circuit tunnel.
