Tools for Assessing Performance: FY23-Q1 Report [Slides]

LANL was tasked with working with NREL to implement QUIC within the TAP API by the end of Q1, FY2023. If QUICURB cannot be implemented in a way that it can be run outside of the QUIC platform, there will be no further R&D funding for QUIC development. QUIC includes a graphical user interface that imports and preprocesses the various input data streams (3D building databases, ambient wind, vegetation, etc.) and writes them in a format that the QUICURB Fortran executable requires. In order to interface with the TAP API, a Python script was developed that would replace the functionality previously only available within QUICGUI. LANL worked with NREL to test the Python script to ensure that it was operation and fulfilled the requirements.

Tools Assessing Performance (FY2022 Quarter 4 Report)

We were finally successful in acquiring TTU’s 200-meter tower data for the duration of the Isolated Building Wake Experiment (IBWE). This data will provide an independent measurement of the undisturbed wind profile including heights far above those that are typical of meteorological sensor networks. These measurements will characterize the mean and turbulence throughout the atmospheric surface layer, which will be particularly useful for validation of highfidelity computational fluid dynamics models. This dataset can be shared freely among the TAP team but not outside of it as TTU sells this data to the wind power industry. The journal article overview has been submitted to LANL’s publication review and will be submitted to the Journal of Wind Engineering and Industrial Aerodynamics once the review is complete. We are nearing completion on another two articles. The first discusses analyses of the evolution of the measurements of mean wind speed along the centerline of the building as a function of atmospheric stability. Rather than using individual time steps, all of the wind speed measurements are normalized using the upwind measurement at 2 building heights (H) and filtered by wind direction and atmospheric stability. The second discusses the development of the diffusive wake model and uses the averaged profiles from the first article to validate the behavior of the model. The portion of the section below on the diffusive wake model discussing comparisons with the averaged profiles, will be included in the validation section of this paper.
