Mesh quality and solution accuracy

It is a known fact that mesh having low quality( skew ,aspect ratio) produces poor results(CFD/FEA). Any maths/procedure which correlates skew or aspect ratio to the solution accuracy exist ? Thereby we can correct the solution latter.
In my case(2D) skewed cells produce abnormal gradient ( without limiter) with cell centered formulation. But node based gives better results.
Any suggestion , research papers ?
