Complex chemical and fluid dynamic mechanisms present in combustion systems necessitate the validation of computational fluid dynamics (CFD) models using flow visualization and velocity field measurement techniques. Two cutting edge measurement techniques for reacting flows are planar-laser induced fluorescence (PLIF), which images combustion radicals within the flame, and stereoscopic particle image velocimetry (sPIV), which is a non-intrusive laser-based velocity measurement. These measurements and others are often synchronized and coupled together to gain a complete picture of flow field variation (i.e. pressure, temperature, velocity, etc.). The PIV measurement in particular poses a variety of challenges especially during the data processing phase which can be achieved using either commercial or open-source software packages. This papers explores the qualitative difference between each software with the intent of providing a recommendation on which form of software should be used. By understanding the types of software that should be used, one can develop lab infrastructure that maximizes the effectiveness of using said software.
