TY - JOUR TI - Kelvin-Helmholtz discontinuity in two superposed viscous conducting fluids in a horizontal magnetic field AU - Khan Aiyub AU - Sharma Neka AU - Bhatia P K JN - Thermal Science PY - 2008 VL - 12 IS - 3 SP - 103 EP - 110 PT - Article AB - The Kelvin-Helmholtz discontinuity in two superposed viscous conducting fluids has been investigated in the taking account of effects of surface tension, when the whole system is immersed in a uniform horizontal magnetic field. The streaming motion is assumed to be two-dimensional. The stability analysis has been carried out for two highly viscous fluid of uniform densities. The dispersion relation has been derived and solved numerically. It is found that the effect of viscosity, porosity and surface tension have stabilizing influence on the growth rate of the unstable mode, while streaming velocity has a destabilizing influence on the system.
