Abstract
Aspects of the present disclosure may include methods for assessing high resolution skin friction fields generated by at water moving across at least a portion of an object surface, the method including covering the at least a portion of an object surface with a layer of oil film comprising a luminescent dye; placing the object in moving water; 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 object.
Claims16
A method for assessing high resolution skin friction fields generated by at water moving across at least a portion of an object surface, the method comprising
- covering the at least a portion of an object surface with a layer of oil film comprising a luminescent dye;
- placing the object in moving water;
- 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 object.
A system for assessing high resolution skin friction fields generated by at water moving
- across at least a portion of an object 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 an object surface, wherein the oil film comprising a luminescent dye is capable of differential luminescence based on oil-film thickness;
- a water channel capable of moving water at a uniform velocity;
- an acquisition device to acquire luminescence data;
- and
- a light source capable of causing the luminescent dye to luminesce.
