- Abstract
- There were many experimental studies on measuring the water impact load. The pressure sensor has been widely used to measure the water impact pressure, but accuracy of pressure sensor has not been investigated thoroughly. The present study considers accuracy of pressure sensor for the water impact problem. For this purpose, different types of pressure sensors were attached on 2D wedge surface and water impact pressure was measured during free falling of wedge. Those pressure sensors have different types, sensing areas, and sensitivity. The peak pressure and rise time measured from the different pressure sensors were compared each other. Based on these results, the uncertainties and reliability of pressure sensor on the measurement of water impact load are discussed. ？ Copyright 2016 by the International Society of Offshore and Polar Engineers (ISOPE).
