Air-Aided Shear on a Thin Film Subjected to a Transverse Magnetic Field of Constant Strength: Stability and Dynamics

Figure 7

Variation of 𝑘 with respect to Re when 𝛽=50^∘ and 𝑆=5: (1)𝐶_𝑅<0 and 𝐽₂<0; (2)𝐶_𝑅<0 and 𝐽₂>0; (3)𝐶_𝑅>0 and 𝐽₂<0. The strip enclosing asterisks indicates that 𝐶_𝑅>0 and 𝐽₂>0. The broken line within the strip represents 𝑘_𝑚=𝑘_𝑐/√2.
