Osborne Reynolds
claimed by Charlene Walton (cwalton8) 12.05.2015
Osborne Reynolds (August 23 1842 – February 23 1912) was the pioneer and main contributor of fundamental fluid dynamics. His scientific research on flow contributed to the Reynolds number, Reynolds analogy, Naiver-Stokes equation, Reynolds stress and Reynolds decomposition in order to predict the speed and mass of fluids at a given period of time.
Personal Life
Early Life
Osborne Reynolds was born in Belfast, Ireland to Osborne Reynolds Sr. He followed the footsteps of his father and attended Queen's college and graduated in 1867 as the seventh wrangler in mathematics. He soon after worked in London with Lawson and Masergy but focused more on his academic research and teaching a year later when he was elected the first professor of engineering at Owen's College. During his first years as a chair, Osborne career began rocky. During his time as chair, Osborne marries Charlotte Jemima Chadwick, who, unfortunately dies from peritonitis during child birth. After her death, Osborne steps down as chair and focuses more on his teaching, research and his newly born son. During his initial years as a teacher, Osborne was forced to focus on "out of door" physics (i.e. tails of comets, solar corona,electric properties of clouds), since he did not have a physics research lab available to him to conduct research. This initial focus on "out of door" sparked his interest in fluid dynamics and hydrostatics. His focuses shifted from calculating and observing tails of comets to formation of raindrops and understanding how tree trunks burst after being struck by lighting. His observational studies had lead to the formation of his first significant study on the link between friction and heat transfer. His interest progressed on fluids and flow centered around surface waves deep in the ocean and fluid pipes used in machinery. However, his lack of a physics laboratory limited his scientific contributes. It was not until 1887, after much convincing of the Senate, that Reynolds was able to obtain his own research laboratory. It was in his laboratory that he was able to formulate equations and experiments that are well known today.
Scientific Career
In 1877, Osborne was elected fellow of the Royal Society due to his scientific contributions and equations. In 1895, years after Reynolds obtained his scientific research laboratory, Reynolds adopts Reynolds decomposition and Reynolds stress equations. Reynolds decomposition and Reynolds stress equations all seemed from his initial observation studies on friction and heat transfer in order to determine the velocity of a fluid body. The equations help determine the speed of fluids and determine the direction to create a well understood velocity profile of that fluid. His smaller observational and experimental studies created the foundation of his late studies and late paper on determining the mechanical equivalence of heat.
