| Summary: | This report presents the methods and steps taken to design and build an experimental setup that can be used to study the effects of rotation on the discharge coefficient of an orifice. The goal of this project is to develop an experimental apparatus that allows fix tile calculation of the discharge coefficient for airflow through a rotating orifice. Fundamental equations of fluid mechanics or compressible flow were employed to analyze the airflow in the orifice. Nondimensional parameters were then determined to examine the effects that various geometrical physical parameters have on the discharge coefficient. The design of the test setup was broken down into four major subsystems. The four major subsystems are: the plenums, the disk, the sealing mechanism, and the power transmission system. Conceptual designs were developed for each of the subsystem and the final design was developed using the most acceptable conceptual designs of the subsystems. Also this project discusses theoretical developments, safety concerns, testing procedures, and instrumentation. Since the seal has not been received to date, testing of the apparatus has not been performed.
