OpenFOAM cases for the Validation of the CHT Model

This dataset contains the underlying data for the paper " Conjugate Heat Transfer Modeling of a Cold Plate Design for Hybrid-Cooled Data Centers” in Energies Journal.

Numerical simulations are performed using the open-source CFD code OpenFoam. Features of the numerical model described in the paper can be summarized as:

This data set contains OpenFoam cases for the validation of the thermal model with the experimental data in the literature (Saitoh et al. 1993) using both buoyantPimpleFoam and chtMultiRegionFoam solvers.

Saitoh, T.; Sajiki, T.; Maruhara, K. Benchmark solutions to natural convection heat transfer problem around a horizontal circular cylinder. Int. J. Heat Mass Trans. 1993, 36, 1251–1259.

A multi-region unstructured mesh was created using Salome software and exported as unv files. The generated unv files can be found in the corresponding directories.

Allmesh script imports regions from the unv files to the OpenFoam and runs createPatch file for the application of boundary conditions .

Allrun script runs transient simulation using parallel computing.

postProcess script compares case results with experimental results and generates a plot in the directory results.

Flow inside air and water regions are considered as laminar due to the low Reynolds numbers.

Numerical schemes used in the solutions of constitutive equations are carefully selected to obtain results consistent with the experimental data.

A new function object is developed for the calculation of the Nusselt number on the cylinder. This library can be downloaded via the following link and sould be  compiled before cases are run:
