An Experimental Study Of Formation Of Circulation Patterns In Laminar Unsteady Driven Cavity Flows Using Particle Image Velocimeter (Piv) Techniques, Jon Farkas
University of New Orleans Theses and Dissertations
Abstract
An experimental study is conducted to determine the velocity fields, from development to steady state, in a square enclosure due to movement of a constant velocity lid using Particle Image Velocitmetry (PIV). Experiments were conducted with water, seeded with hollow glass sphere particles 10 microns in diameter, at three different lid velocities leading to Reynolds numbers in the high laminar to transitional range. Driven Cavity Flow is a classic fluid dynamics case often used for benchmarking of computational codes. Previous work has primarily focused on improving computational codes, experimental work is lacking and focused on obtaining steady state readings. …
