A Linear Stability Analysis of Thermal Convection in a Fluid Layer with Simultaneous Rotation and Magnetic Field Acting in Different Directions

Table 6

Critical Rayleigh numbers and wave numbers at marginal stability for the onset of stationary convection when both bounding surfaces are rigid. Gravity vector 𝐠 parallel to the magnetic field vector 𝐇. 𝑄 is the dimensionless magnetic parameter. 𝑅 is the Rayleigh number obtained by the Tau Chebyshev method. 𝑅_Ch is the Rayleigh number obtained by Chandrasekhar [1].
