Excalibur New Member Erik Thyil Join Date: Sep 2015 Posts: 8 Rep Power: 10	The classical approach for 1d hot wire anemometer experiments is simply doing an fft analysis for a time resolved data taking sampling frequency into account. However, i couldnt find much info for calculating spatial spectrum where the largest and the smallest scales in the flow would be calculated. Additionally, do you have any idea how to filter a turbulence box. i have some signal filtering knowledge but i am not sure if it is directly applicable to a flow field data.
