A novel volumetric velocity measurement method for small seeding tracers in large volumes
نویسندگان
چکیده
This paper presents the volumetric velocity measurement method of small seeding tracer with diameter 5µm ∼ 100µm for volumes ≥ 500cm3. The size is between helium-filled soap bubbles (HFSB) and di-ethyl-hexyl-sebacic acid ester(DEHS) droplets. targeted volume dimension equivalent to HFSB, which will give a higher resolution turbulence study. relations particle size, imaging light intensity are formulated. estimation results computed setup design. Finally, methodology demonstrated measurements in jet flow, velocities averaged 15µm air filled measured 7200cm3.

Tip sensor probe for changing refractive index measurement in small volumes
In this paper, a tapered tip optical fiber probe sensor for localized refractive index (RI) measurements is presented. This sensor’s interaction with analytes is confined to a few micro-meters which makes it a promising candidate for in-vivo or even intra-cellular RI monitoring. This tapered tip was simply fabricated by etching optical fiber with hydrofluoric acid to a conic shape with a sub-m...
متن کاملA Novel Method for Human Astigmatism Formulation and Measurement
Astigmatism’s defect has not yet been formulated in Physics and medical physics books theoretically. In this paper, we are trying to formulate the astigmatism’s defect. The results of formulation show that “the degree of astigmatism is negative reverse the distance that vision’s condition of astigmatism’s chart lines change conditions in dimness angle from dimness condition at infinite distance...

متن کاملVelocity Measurement System for Small Caliber Projectiles
The use of state of art instrumentation systems to measure high-speed events has increased tremendously in the past few decades. The current study aimed at measuring the velocity of small caliber projectiles within the desired limits of accuracy. The velocity of the projectile is calculated by dividing the distance between two downrange measurement locations, by the difference of the time when ...
