Hi All,

I simulated the fluidized bubbling bed and used the sampling option in fluent to calculate time averaged data. The time averaged axial particle velocity is coming out as shown. When I exported the data and plotted in MATLAB the graph was a bit different. In the attached graph, the velocity at the extreme ends i.e. near the walls has come out non-zero but the instantaneous plots at every recorded time step shows zero velocity. Does fluent use normal arithmetic mean average of the data at every time step at a particular location or there is some other method to evaluate time averaged data. I searched the fluent guide but did not find any information on this.

Fluent uses arithmetic averages at cells to compute field averages yes. But I'm not sure what we're looking at here because mean fields have the name Mean before them. I also have no clue what time averaged particle velocity is or what that means because that's not a field. Maybe it is beyond my experience but as far as field averages go, that's how they work.
