This is the current test setup to obtain Cd of the fuel flow. For the first test, the film cooling holes will not be drilled yet, and so no leakage will occur unless the O-rings fail. The aluminum carrier underneath the injector is to inlet fuel and prevent that fuel from leaking; in the second image, you can see the fuel port coming from the bottom of this carrier. We The port on the right in the first image will link to a pressure transducer. We intend on performing multiple water flow tests across different injector dP's to properly characterize Cd.
