摘要：The linear stability of plane Poiseuille flow at low Reynolds
number of a conducting Oldroyd fluid in the presence of a
transverse magnetic field has been investigated numerically.
Spectral tau method with expansions in Chebyshev polynomials is
used to solve the Orr-Sommerfeld equation. It is found that
viscoelastic parameters have destabilizing effect and magnetic
field has a stabilizing effect in the field of flow. But no
instabilities are found.
