AIAA Scitech 2021

Computation and comparison of the stable Northeastern US marine boundary layer

Everything to know and do for the Scitech paper

Paper objectives

What did we promise to do?

  • Continue offshore ABL computations from the Torque 2020 study --> include stable conditions
  • Compare stable ABLs with neutral and unstable
  • Examine what happens to statistics (spectra, turbulent length scales, etc.) as a function of height
  • Compare AMR-Wind vs Nalu-wind results for offshore ABLs.

Getting started

Here's everything that's been done so far

Previous papers/publications

Take a look at some of the previously published items

Previous runs

Neutral and unstable have already been completed

  • Outline of cases: A jupyter notebook summarizing the targeted conditions for stable, unstable, and neutral (based on Archer et al)
  • NaluWindRuns neutral: Directory of neutral Nalu-Wind input files for neutral 5m/s, 10m/s and 15 m/s
  • NaluWindRuns unstable: Directory of unstable Nalu-Wind input files for neutral 5m/s, 10m/s and 15 m/s

Postprocessing

Work under way

  • NaluWindRuns for stable: Runs completed for stable 5m/s, 10m/s and 15m/s
    o Each run for 20,000 secs on 3km x 3km x 1km domain
    o Averaged mean profiles gathered
    o Need to update spectra and lengthscale -- results for scitech abstract on small domain

To do for scitech

  • Lawrence: upload all python stats calculation scripts to Github
  • Complete statistics (lengthscale and spectra) for stable runs
  • Run matching AMR-Wind cases for stable ABL's (high priority)
  • Write equivalent stats calculation scripts (lengthscale) for AMR-Wind cases
  • Collect and compare stats for AMR-Wind cases
  • Run matching AMR-Wind cases for neutral and unstable ABL's (lower priority)

and of course,

  • Write Scitech paper!
