Abstract
A majority of simulation methods that have been used in the past, involve the placement of geometric shapes at a section of the wind tunnel; as the air flows around these geometries positioned at a pre-defined spacing, the atmospheric boundary layer is generated. This report studies a method named Cowdrey's, and analyzes its application in a wind tunnel with a contracted inlet. Through this method, rods are installed in a wind tunnel to measure the profile of an atmospheric boundary layer. The project analyzes a procedure for calculating the number, spacing and diameter of the rods installed at the inlet and settling chamber, and graphs the expected profile on placing the rods. On a grand scheme, this project is required for wind tunnel testing, to estimate the wind loads acting on a ship model that will further impact its performance and safe operating envelope.
Did this research project receive funding support (Spark, SURF, Research Abroad, Student Internal Grants, Collaborative, Climbing, or Ignite Grants) from the Office of Undergraduate Research?
