Abstract
The invention discloses an oil formula for low-speed wind tunnel fluorescent oil flow friction force field measuring experiments. The oil formula comprises a fluorescent agent and carrier oil, wherein the mass ratio of the fluorescent agent to the carrier oil is 1:30; the fluorescent agent is an automobile fluorescent leak detection agent; the carrier oil is methyl silicone oil with the kinematic viscosity of 1,000 cs. The oil formula is simple and fast in matching and is suitable for fluorescent oil flow friction force field measuring experiments of common low-speed wind tunnels with the wind speed range of 20-60 m/s.
Description
Technical field
The present invention relates to a kind of formula of oil for the test of low-speed wind tunnel fluorescent oil flow friction force field measurement.

Embodiment 2
Oil plant using method is as follows:
Step one: the raw material dosage estimating the test of oil stream according to the area of test model and formula of oil;
Step 2: take fluorescer with electronic scale, precision need higher than 1%;
Step 3: take carrier oil plant with electronic scale, precision need higher than 1%;
Step 4: the fluorescer weighed by proportioning and carrier oil plant are placed in suitable container;
Step 5: stir color by stirring rod even;
Step 6: leave standstill about 30 minutes before the test;
Step 7: if the oil plant time of repose prepared is long, repeats step 5, step 6; With a small amount of anhydrous alcohol wiping model surface, after anhydrous alcohol volatilizees completely, with the oil plant of standing about 30 minutes is quick, the even scrubbing brush of oil painting scrubbing brush on model surface;
Step 8: start rapidly wind-tunnel after brushing to the test wind, the test of fluorescent oil flow friction force field measurement is carried out to model.
