Abstract
Aspects of the present disclosure may include systems and methods for assessing high resolution surface pressure fields generated by air moving across at least a portion of a bluff body, the method including covering the at least a portion of the surface of the bluff body with a layer of oil film comprising a luminescent dye; placing the bluff body in moving air with a constant velocity; assessing the luminescence of the dye in at least two consecutive time periods, wherein the luminescence of the dye is related to the thickness of the oil film at one or more locations on the surface of the bluff body.
Claims17
A method for assessing high resolution surface pressure fields generated by air moving across at least a portion of a bluff body, the method comprising
- covering the at least a portion of the surface of the bluff body with a layer of oil film comprising a luminescent dye;
- placing the bluff body in moving air with a constant velocity;
- assessing the luminescence of the dye in at least two consecutive time periods,
- wherein the luminescence of the dye is related to the thickness of the oil film at one or more locations on the surface of the bluff body.
A system for assessing surface pressure generated by air moving across at least a portion of an bluff body surface, the system comprising:
- an oil film comprising a luminescent dye, wherein the oil film is capable of being uniformly spread in a thin film across a bluff body surface, wherein the oil film comprising a luminescent dye is capable of differential luminescence based on oil-film thickness;
- a wind tunnel capable of moving air at a uniform velocity and containing the at least a portion of a bluff body;
- an acquisition device to acquire luminescence data;
- and
- a light source capable of causing the luminescent dye to luminesce.
