Ships at sea are affected not only by water but also by wind. Especially for vessels with large superstructures such as container ships and car carriers, wind forces can cause significant resistance, reducing ship speed. We measure the wind pressure acting on the superstructure and evaluate its performance.
Wind Tunnel Test
We measure the static force (six component aerodynamic force) acting on the model by the wind. Changing the wind direction to the model, we can check the maximum and minimum values of wind pressure force.
We visualize airflow around the model by smoke. By observing the airflow, we can confirm the separation and stagnation of the flow and obtain guidelines to improve shapes.
We conduct wind resistance and aerodynamic performance tests for bridges, harbor cranes, etc. in our low-speed wind tunnels of a horizontally circulating style. Typical tests include static aerodynamic force measurement tests to determine static aerodynamic forces and spring-supported tests to determine vibration response characteristics to wind.
