Abstract
Abstract A method and apparatus for fluid flow visualization of the fluid stream about a model in a fluid circulating facility. An infrared camera is directed at a model through a window in the facility and due to the temperature differential between the model and the fluid, displays the freestream around the model.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
76 words
A method of visualizing the fluid stream around an object mounted in a fluid circulating facility comprising the steps of: placing an object within a fluid circulating facility; circulating a fluid within the facility and around said object; establishing a temperature difference between said fluid and said object; detecting the infrared radiation from the fluid and the object with an infrared camera; and displaying the detected infrared radiation pattern of the fluid stream around the object.
Claim 2
Independent Claim
76 words
A method of visualizing the fluid stream around an object mounted in a fluid circulating facility comprising the steps of: placing an object within a fluid circulating facility; circulating a fluid within the facility and around said object; establishing a temperature difference between said fluid and said object; detecting the infrared radiation from the fluid and the object with an infrared camera; and displaying the detected infrared radiation pattern of the fluid stream around the object.
Claim 3
Independent Claim
62 words
A method of visualizing the fluid stream around a body in a fluid circulating facility, comprising: circulating a fluid in the facility around a body; establishing a difference in temperature between the fluid and the body; detecting the infrared radiation indicative of the temperature difference between the fluid and the body; displaying the pattern of the detected infrared radiation for visual observation.
Claim 4
Independent Claim
62 words
A method of visualizing the fluid stream around a body in a fluid circulating facility, comprising: circulating a fluid in the facility around a body; establishing a difference in temperature between the fluid and the body; detecting the infrared radiation indicative of the temperature difference between the fluid and the body; displaying the pattern of the detected infrared radiation for visual observation.
Claim 5
Independent Claim
59 words
A method of visualizing fluid flow around an object comprising the steps of: mounting an object in a fluid circulating facility; circulating a fluid in said facility and about the object; establishing a temperature differential between the object and the fluid; detecting the infrared radiation of the fluid flow about the object; displaying the infrared pattern for visual observation.
