LES-bplume provided numerous sets of Eulerian data for Temperature and Velocities in .csv format (UVW and T). Data corresponds to the Pure Thermal Plumes simulated in Large Eddy Simulation framework of Weather Research and Forecast model v 4.0. Flow axial direction is z-axis (+ve up), Radial directions are X- and Y-axis. The source diameter D = 400 meters located at the center of the domain bottom boundary.

Boundary conditions:

• Bottom boundary - specified heat-flux 

• Top boundary - pressure top

• Lateral boundaries - periodic

Eulerian details:

• Domain size for Eulerian data: nx * ny *nz * nt = 45*45*700*500

• Grid size:

  • dx = 40m​​

  • dy = 40m

  • dz = 10m

  • dt = 10s

• Center-line is at grid point (i,j) = (23,23)  in Matlab or  (22, 22) in python.

• Initial Conditions for all cases are same: No winds and No stratification.

• Output provided at every 10 seconds, i.e. for 90 mins of simulation done 541 time-steps are recorded, first time-step is initial forcing should be ignored for processing.
