VELOCITIES OF CONVECTIVE ASCENDING FLOW IN LIQUID-DOMINATED HYDROTHERMAL CONVECTION SYSTEMS

Velocities of convective ascending flow in hydrothermal convection systems show typical characteristics. From simple one-dimensional analyses based on static temperature logging data, it was found that the macro velocities of convective ascending flow in active convection systems approach to given order of value. It may be closely related to the structure of permeability and consequently to the stress condition partially. Simulation studies for liquid-dominated hydrothermal systems were also conducted in order to clarify the effects of the permeability or the stress condition on the velocities of ascending flow.
