#Soltrace ls3 code#
If you would like to submit code to fix an issue or add a feature, you can use GitHub to do so. If you would like to report an issue with SolTrace or make a feature request, please let us know by adding a new issue on the issues page. Build the projects in the following order, and assign the environment variable for each project before you build the next one: In Windows, create the WXMSW3 environment variable on your computer to point to the wxWidgets installation folder, or Linux, create the dynamic link /usr//local/bin/wx-config-3 to point to /path/to/wxWidgets/bin/wx-config.Īs you did for wxWidgets, for each of the following projects, clone (download) the repository, build the project, and then (Windows only) create an environment variable pointing to the project folder.
#Soltrace ls3 windows#
The desktop version of SolTrace for Windows or Linux builds from the following open source projects: For details on integration with SAM, see the SAM website. For more details about SolTrace's capabilities, see the SolTrace website. The creation of the code evolved out of a need to model more complex solar optical systems than could be modeled with existing tools. Although ideally suited for solar applications, the code can also be used to model and characterize many general optical systems.
#Soltrace ls3 software#
SolTrace is a software tool developed at NREL to model concentrating solar power (CSP) systems and analyze their optical performance. Otherwise, the verifications against previously models in AZTRAK platform certify the necessity to correct the standard HTC, but the absence of absorber thermal profiles experimental data inhibits its validation.The SolTrace Open Source Project repository contains the source code, tools, and instructions to build a desktop version of the National Renewable Energy Laboratory's SolTrace. The involvement of a CF in the DISS facility improves the accuracy of absorber cross-section thermal gradients predictions, reducing the mean deviations from 22.2 % (without considers it) to 6.9 %. The heat transfer variables mean deviations are lower than 2.4 % and 7.0 % for AZTRAK and DISS facilities, respectively. The model is validated in the AZTRAK platform and the superheated steam region of the DISS facility under steady-state conditions. The suggested CF is based on the azimuthal local Nusselt reported in past studies for circumferentially-varying BCs, and on the absorber experimental data from the Direct Solar Steam (DISS) test facility.

Its main novelty is to involve a correction factor (CF) in the standard heat transfer coefficient (HTC) correlations for uniform boundary conditions (BC), due to their inability to correctly predict the absorber thermal profiles. The model is solved using the finite volume method, involving the NUFHD through a Monte Carlo ray-tracing method implemented in SolTrace. In the present work, a realistic 3D HCE − 1D HTF model under an unsteady formulation of the partial differential equations is implemented to properly calculate the receiver thermal distribution. As an alternative, 3D HCE models coupled to 1D heat transfer fluid (HTF) problem results in a much lower computational cost and accuracy enough. Several 3D numerical studies have been implemented using computational fluid dynamics (CFD) commercial software, but with high computational effort. Obtaining 3D temperature fields involving the non-uniform heat flux distribution (NUHFD) around the receiver becomes an essential matter for modelling and simulation tools. The prediction of thermal distributions around the heat collector element (HCE) is a key issue for the safety and efficiency in parabolic-trough solar collectors.
