Stability of parallel non-newtonian flows

De-/anti-icing fluids are sprayed on aircraft wings to prevent dangerous loss of performance due to ice formation. The residual layers of such fluids which may either be of newtonian or non-newtonian character could also adversely effect the performance of the aircraft. Therefore it is important to investigate the stability characteristics of such fluids. Stability problem for non-newtonian fluids (power-law fluids in particular) has been solved using the linear stability theory for nearly parallel flows.
