participated includes: blow-down thermodynamics, ignition of metals, non-isothermal heat transfer, zero-g fluid mechanics, turbulent boundary-layer flow structure, turbulence-wall interactions, stability of gas films, hydrodynamic stability, boundary-layer calculation methods, surface-tension-driven flows, organized waves in turbulent shear flows, turbulence computation, unsteady turbulent boundary layers, internal combustion-engine-cylinder flows, unsteady jets and separating flows, turbulence modeling, flow control, microelectromechanical systems (MEMS), and large eddy simulation (LES) of turbulent flows.
Bill was one of the first to embrace the computer, and he authored programs for his own work, many of which were subsequently used by others worldwide in teaching and research. His program for chemical equilibrium analysis, STANJAN, for example, is used at more than 100 universities in the United States and around the world. In 1971, he and Joel Ferziger initiated the highly successful turbulence simulation program at Stanford. Bill pioneered the introduction of the LES technique in engineering analysis, which is widely used today .
Bill’s honors included fellowships of the American Society of Mechanical Engineers (ASME) (1979) and the American Physical Society (APS) (1982), election to the National Academy of Engineering (1979) and the American Academy of Arts and Sciences (1995), and the Fluid Engineering Award of ASME (1989) and Otto Laporte Award from APS (1992).
Bill was an outstanding teacher. His knowledge was deep, his ability to explain difficult concepts was exceptional, and his passion and enthusiasm in the classroom were legendary. With unusual clarity of thought and “out-of-the-box” design of problems, his textbooks on thermodynamics are standouts in the field. Strongly physics-based and very fundamental in their approach, his textbooks reveal a depth of understanding that makes for both solid teaching and a satisfying read.
Besides being an outstanding research scientist and teacher, Bill Reynolds was a classic do-it-yourselfer in the great tradition of American engineering. He could often be seen in the department workshop on weekends, working on a piece of hardware, academic or domestic. He designed and built his Los Altos home,
