Tutorial 10 - Helideck Turbulence

 

As of version 1.34, in addition to the typical SST turbulence model, in:Flux comes included with a Reynolds Stress Transport Model (RSTM) for performing helideck turbulence studies which can be used to comply with regulations like CAP437 and NORSOK C-004.

 

The RSTM solves 7 different turbulence equations, rather than the 2-equation SST model used for standard analyses. The additional turbulence equations of the RSTM are used to solve the necessary vertical velocity fluctuations variable needed for helideck turbulence studies.

 

Once a simulation has been defined using the RSTM a new post-processing variable called Vertical Fluctuating Velocity, m/s will be available. Additionally, a more sensitive mesh adaption will automatically be applied to capture the complex turbulence generation.

 

 

In this tutorial you will learn how to:

• Setup and Run a ventilation simulation with the RSTM

• Review results with the vertical fluctuating velocity variable
