This FORTRAN program lays the basic fundamentals for programming turbulence models to solve realistic turbulent flows. As a fundamental, extendable platform, the program uses the Prandtl turbulence model to consider a 1D Couette flow. In this specific situation, the program solves the x-momentum equation for the u-velocity and the turbulent kinetic energy (k) partial differential equation. Key output are turbulence velocity, dissipation, and kinetic energy. Extending the program to 2D and 3D is rather straightforward by adding the y and z momentum equations, and noting that the generalized momentum PDEs should be used, as found in chapter 2 of the book. In addition, the Prandtl turbulence model can be replaced with the ω partial differential equation and the relevant 2006 k-ω auxiliary equations, thereby extending the model to the 2006 k-ω Wilcox turbulence model; refer to Section 4.6.3.4 of the book.
Can be used to call Function “NaPbBiLBE.m”.
Calculates the physical properties of molten sodium, lead, bismuth, and lead-bismuth eutectic (LBE). This includes the density, thermal conductivity, heat capacity, dynamic viscosity, and volume expansivity.
Calculates the Reynolds number (Re), y+, the LIKE algorithm, as well as Kolmogorov, Taylor, and integral eddy size, velocity, and time scales. Many examples from the book were added, as well as many that are not in the book, including a “fun” mako shark example. Makos can achieve so much momentum that they are able to surge up to 30 feet above the surface of the ocean.
Auxiliary files for calling the REFPROP material properties calculator. Note that file “Yplus_LIKE_Eddy_Scales__BOOK_Version.m” and file “PR_ETA_FPRIME__BOOK_Version.m” call REFPROP. Alternatively, the user can input their own property values, if they choose to do so.
Useful for laminar and turbulent natural circulation problems. The program calculates the Prandtl number (Pr), the Grashof number (Gr), the Nusselt number (Nu), and the Rayleigh number (Ra), as well as many other flow properties.
