Numerical Study of a Gas Bubble Rising Through Stagnant Fluid

It is well known that the environment degradation has come along the time positioning as one of the main problems from modern world. Among several questions of the environmental interest the methane bubble rise in the lakes can be emphasized, from the anoxic sediment in the bottom of lake until water interface atmosphere. In particular, the present academic work has come to treat mathematic modeling of the bubble rise through sediment viscous fluid near the bottom lake and present results, via Mathematics and Computing-Numeric Simulation, about the terminal velocity ascent of the bubble.
