# 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

**---to be continued---**

## 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
