Keywords
  • Bolund Measurements Were Used For A Blind Comparison Of Microscale Flow Models
  • Fifty-Seven Models Ranging From Numerical To Physical Were Used
  • Including Large-Eddy Simulation (Les) Models
  • Reynolds-Averaged Navier–Stokes (Rans) Models
  • And Linearized Models
  • In Addition To Wind-Tunnel And Water-Channel Experiments
  • Many Assumptions Of Linearized Models Were Violated When Simulating The Flow Around Bolund
  • As Expected
  • These Models Showed Large Errors
  • Expectations Were Higher For Les Models
  • However
  • Of The Submitted Les Results
  • All Had Difficulties In Applying The Specified Boundary Conditions And All Had Large Speed-Up Errors
  • In Contrast
  • The Physical Models Both Managed To Apply Undisturbed ‘Free Wind’ Boundary Conditions And Achiev
  • The Most Successful Models Were Rans With Two-Equation Closures
  • These Models Gave The Lowest Errors With Respect To Speed-Up And Turbulent Kinetic Energy (Tke) Pred
