摘要：
The authors consider finite element approximations for a particular algebraic model of turbulence. They give an algorithm and study its properties, including estimates for the error in the finite element approximation. The model they study is typical of zero equation models. The resulting governing equations are similar in appearance to the Navier-Stokes equations; the complicating factor is the appearance of a nonlinear viscosity coefficient in the viscous terms. 5 Refs.
