PIV-data-process

Some codes used to process the fluid experiments data aquried by PIV(Particle Image Velocimetry) sysytem

Input file:

the .mat file exported from the PIVlab on MATLAB

Output results:

1. the time-avereaged velocity
2. the turbulent velocity
3. the turbulent kinetic energy dissipation rate

Source Code Description

Velocity.py:

        load mat file and calculate the velocity

Smooth.py:

        define a moving average function

        the median average algorithm is used here
        
        require input as 1-d array and the output is a 1-d array, too 

DissipationRate.py:

        define a function to compute the turbulent kinetic energy dissipation rate
          
        need the turbulent velocity as input (a 3-d array here)
                 
        the output is a 3-d array of the dissipation rate
