Numerical study of an individual Taylor bubble rising through stagnant liquids under laminar flow regime

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 mod...

Taylor bubble rising in a vertical pipe against laminar or turbulent downward flow: symmetric to asymmetric shape transition

Numerical Simulation of Laminar Separation-Bubble Control

In the present paper an active control mechanism for the control of laminar separation bubbles on airfoils is investigated by means of direct numerical simulation and linear stability theory. Boundary layer instabilities excited by periodic oscillations are utilized to control the size and length of the separation bubble and to make it finally disappear when desired. Unlike traditional vortex g...

numerical study of the effect of surface roughness and bubble injection on skin friction in taylor-couette flow

in this research, the effect of surface roughness and bubble injection on skin friction and hydrodynamic drag force has been numerically considered. this research is based on taylor-couette flow. considered flow includes two concentric cylinders which internal cylinder is movable and external is immovable. the effective equations on the flow includes: equations of momentum, continuous, turbulen...
