Abstract: Water contains oxygen which may make a human
breathe under water like a fish. Centrifugal separator can separate
dissolved gases from water. Carrier solution can increase the
separation of dissolved oxygen from water. But, to develop an
breathing device for a human under water, the enhancement of
separation of dissolved gases including oxygen and portable devices
which have dc battery based device and proper size are needed.
In this study, we set up experimental device for analyzing
separation characteristics of dissolved gases including oxygen from
water using a battery based portable vacuum pump. We characterized
vacuum state, flow rate of separation of dissolved gases and oxygen
concentration which were influenced by the manufactured vacuum
pump.
Abstract: A prototype model of an emulsion separator was
designed and manufactured. Generally, it is a cylinder filled with
different fractal modules. The emulsion was fed into the reactor by a
peristaltic pump through an inlet placed at the boundary between the
two phases. For hydrodynamic design and sizing of the reactor the
assumptions of the theory of filtration were used and methods to
describe the separation process were developed. Based on this
methodology and using numerical methods and software of Autodesk
the process is simulated in different operating modes. The basic
hydrodynamic characteristics - speed and performance for different
types of fractal systems and decisions to optimize the design of the
reactor were also defined.
