摘要：

We propose the results of a theoretical and mathematical model of the growing bubbles at low Mach number in a generalized Newtonian fluid. The system occurs under the effect of magnetic field and shear stress. The mathematical model is formulated and solved analytically on the basis of mass equation, Navier-Stokes equation, and diffusion equation. Analysis of the results demonstrates the role of magnetic field, shear stress, and electrical conductivity on the bubble growth process in a generalized Newtonian fluid at low Mach number; gives us the bubble radius in non-Newtonian fluid, Newtonian fluid, and viscoelastic fluid in the special cases of the flow index n; and also we get that the effect of magnetic field weakness from the behavior of gas bubble growth.</p>
