Many undergraduate and early graduate engineering programs offer courses in numerical analysis to teach students how to solve partial differential equations numerically and fluid mechanics to teach how the Navier-Stokes equations govern fluid phenomena. However, the connection between numerical analysis taught in the classroom and CFD is very rarely made. In an effort to bridge the gap, a simplified CFD simulation was developed to model the diffusion of a two dimensional turbulent water jet. Assumptions were made to simplify the Navier-Stokes equations in cartesian coordinates to arrive at a single PDE with only three terms. Considering that the modeled water jet is fully turbulent (Re ≈ 150,000), an algebraic turbulence model was incorporated to account for turbulent viscosity effects, namely Prandtl’s Mixing Length model. Velocity measurement and flow visualization were conducted using a water table to validate the model. Also, a commercially available CFD program (FLUENT) was employed to evaluate the validity of the simplifications made to the governing equations.
