Abstract
A compilation of MATLAB scripts and functions is provided to enable the user to quickly estimate key laminar and turbulence parameters. This includes the LIKE algorithm, as well as a function to calculate physical properties for various molten metals. Another MATLAB script calculates the peak velocity for laminar and turbulent flows under natural circulation. The script also calculates the convective heat transfer coefficient, Pr, Gr, Nu, and Ra. Finally, a FORTRAN program for the Prandtl one-equation turbulence model is provided. The program is intended as an example to show how RANS models can be coded, as well as to provide some practical guidelines. The program couples the momentum equation with the k PDE to solve a 2D Couette flow. For user convenience, the program writes MATLAB files suitable for plotting k, ε, νt, and \( \overline{u} \).
