Oscillating-grid turbulence in a homogeneous fluid is in equilibrium between the diffusion of turbulent energy and the dissipation rate of the energy. Such a field has been investigated experimentally and analyzed by using the k– ε turbulence model. Vertical and horizontal components of fluctuating velocity have been measured under the vertical oscillation of a square grid. Vertical profiles of five characteristic quantities, the turbulent energy k, the dissipation rate ε, the vertical energy flux F, the eddy viscosity ν t and a lengthscale l t, have been obtained from the measurements. In the model analysis, the governing equations and the boundary conditions have been non-dimensionalized by using the turbulent energy k 0 and the dissipation rate ε 0 which are given virtually at the center of the grid oscillation as boundary conditions. Dimensionless analytical solutions of k, ε, F, ν t and l t have been derived. The experimental data show some relationships existing between the analytical solutions. This shows the application of the k– ε model to the oscillating-grid turbulence to be valid. The analytical solutions include three model parameters. Their values have been determined from the experimental data. The values of k 0 and ε 0 have been evaluated by superposing the analytical solutions of k, ε and F on their experimental data, and have been related empirically to the experimental parameters. Using the empirical relations for k 0 and ε 0 and the analytical solutions, we can estimate k, ε, F, ν t and l t of the oscillating-grid turbulence.
