Abstract:

Guidance is presented for the use of physical models in the study of reservoir hydrodynamic processes. Modeling theory is developed by nondimensionalizing the Navier-Stokes equations of fluid motion. Examination of these nondimensional equations shows that complete dynamic similitude between prototype and model is achieved by the equating of respective Froude and Reynolds numbers. Although such an equation is not possible if water is the model and prototype fluid, similitude is still maintained if the model and prototype Froude numbers are equated and if the fundamental character of prototype flow turbulent is maintained in the model. Scaling relationships for undistorted and distorted models are presented and the appropriate use of each is discussed. Examples of the application of the relationships presented are given in some detail. An extensive list of publications documenting site-specific and research investigations involving physical modeling is also provided. Keywords Density currents, and Water resources.
