August 25, 1934 – March 28, 2021 Born and raised in Turkey, Tuncer Cebeci graduated from Robert College, Turkey, with B.S. degrees in electrical and mechanical engineering. He came to North Carolina, where he received an M.S. degree in mechanical engineering from Duke University. In 1961, he discovered the love of his life, a Duke undergraduate student from Winston-Salem named Sylvia Ann Holt. Tuncer and Sylvia were married in 1963 at New Hope Methodist Church in Winston-Salem. After receiving his doctorate in mechanical engineering from North Carolina State in 1964, Tuncer, Sylvia, and their new daughter Rabia moved west to Long Beach, where Tuncer joined Douglas Aircraft Company as a research scientist. He was promoted to head of the aerodynamics research department in 1974 and eventually become the company’s first senior fellow in 1982.Tuncer received the prestigious Fluid and Plasma Dynamics Award from the Institute of Aeronautics and Astronautics (AIAA) in 1984. He also became the first distinguished professor in the mechanical engineering department of California State Unive

Cebeci–Smith model

The Cebeci–Smith model, developed by Tuncer Cebeci and Apollo M. O. Smith in 1967, is a 0-equation eddy viscosity model used in computational fluid dynamics analysis of turbulence in boundary layer flows. The model gives eddy viscosity, , as a function of the local boundary layer velocity profile. The model is suitable for high-speed flows with thin attached boundary layers, typically present in aerospace applications. Like the Baldwin-Lomax model, it is not suitable for large regions of flow separation and significant curvature or rotation. Unlike the Baldwin-Lomax model, this model requires the determination of a boundary layer edge.

Equations

In a two-layer model, the boundary layer is considered to comprise two layers: inner (close to the surface) and outer. The eddy viscosity is calculated separately for each layer and combined using:

where is the smallest distance from the surface where is equal to .

The inner-region eddy viscosity is given by:

where

with the von Karman constant usually being taken as 0.4, and with
