This thesis analyses the effect of spatial filtering and limited dimensionality of the velocity fields obtained from wall-bounded turbulent flow experiments on the accuracy of the turbulent dissipation rate and Kolmogorov length scale calculated from these velocity fields. The reason behind the difference between the existing research and the current results has been attributed to the peculiar nature of wall-bounded turbulent flows. Some suggestions have been provided to reduce the error due to spatial filtering. The applicability of the current results to different flow configurations and Reynolds numbers has also been discussed.
