This is an old revision of the document!


A PCRE internal error occured. This might be caused by a faulty plugin

===== Color Scaling ===== Various schemes that try to minimize saturation of color in the flowfield. This parameter might have to be changed for each individual eigenvector. I used a velocity field that had a lot of dark patches or saturation points (Im e_11 or eigenflow 10) as the field to do the comparison. All of these have laminar flow added in. {{:gtspring2009:spieker_blog:ub_eigenvectors:ef10_02.png|scale = 0.2}} {{:gtspring2009:spieker_blog:ub_eigenvectors:ef10_03.png|scale = 0.3}} {{:gtspring2009:spieker_blog:ub_eigenvectors:ef10_04.png|scale = 0.4}} {{:gtspring2009:spieker_blog:ub_eigenvectors:ef10_05.png|scale = 0.5}} {{:gtspring2009:spieker_blog:ub_eigenvectors:ef10_06.png|scale = 0.6}} {{:gtspring2009:spieker_blog:ub_eigenvectors:ef10_07.png|scale = 0.7}} {{:gtspring2009:spieker_blog:ub_eigenvectors:ef10_08.png|scale = 0.8}} {{:gtspring2009:spieker_blog:ub_eigenvectors:ef10_09.png|scale = 0.9}} {{:gtspring2009:spieker_blog:ub_eigenvectors:ef10_10.png|scale = 1.0}} I feel that on velocity fields with dark red and blue spots like this, a scaling factor of about .4 is optimal. A scale of ~0.4 smooths streamwise features without completely blurring out the spanwise features. Sorry, I forgot to rescale these before I posted them.
