Experimental Calculation verified with CFD (Computational Fluid Dynamics)

Approximately 20 years ago, before the commercialization of TURBOsplash PAC ®™, the product underwent a rigorous experimental testing and a CDF evaluation aimed for design work.
Since the geometry of TURBOsplash PAC ®™ was not comparable to other existing filling materials, the purpose of the analysis was to carry out a quantitative / qualitative evaluation of the pressure drop and relative efficiency subject to fluids (water and air) inside the cooling tower. A practical evaluation method was used experimentally, performed by independent laboratories that specialize in these of tests. The evaluation parameters, detected experimentally, were analyzed and verified using CFD programs at universities, with the aim to build or verify all cooling towers.
Hence, it was possible to obtain the air pressure drop and efficiency curves in the flow rate air or/and water change. 
Numerical Set-Up (need for CFD calculations)
  • Stationary type simulation
  • Turbulence model: k-ε
  • Solved equation:
    • Continuity
    • Moment of the quantity of motion
    • Turbulent kinetic energy – turbulent dissipation
Boundary conditions
  • Inlet Velocity [FPM]: {150, 300, 400, 500, 600}
  • Outlet static pressure: 0 [Pa] (relative to environmental pressure equal to 101325 Pa)
Experimental / Numeric Comparison
Numerically, it was possible to reproduce the experimental data as overall trend and in terms of absolute value of the air pressure drop.
