William Craig Reynolds (March 16, 1933 – January 3, 2004) was a fluid physicist and mechanical engineer who specialized in turbulent flow and computational fluid dynamics.

[2][3] Reynolds completed his undergraduate degrees, as well as his doctorate, all at Stanford University, in 1954, 1955, and 1957, respectively, after which he joined the faculty.

[4] Reynolds was one of the pioneers in Large eddy simulation for fluid modeling.

[2] He won the Fluid Engineering Award of the American Society of Mechanical Engineers in 1989[5] and the Otto Laporte Award by the American Physical Society in 1992.
