Add a spot of surfactant in the fluid, the frictional resistance of fluid under turbulence state can be significantly reduced, can reach purpose of energy saving.Therefore, surfactant successful Application in fields such as boats and ships transportation, oil exploitation and transportation, water-carriage system.But, at world's energy scarcity, to advocate energetically under the overall background of energy-saving and emission-reduction, the application of surfactant needs constantly to enlarge.To the research that experimentizes of the property of reduction drag of different surfaces activator solution, at the different application field, seek the drag reduction activating agent of performance the best, seem particularly important.
But, in the property of reduction drag of surfactant solution experimentizes process, because the self-characteristic of surfactant solution, under high reynolds number (high flow rate) or temperature flowing situation, will produce a large amount of foams, not only influence the performance of experimental facilities, and influenced the accuracy of experimental result; Especially in experimentation, need the most of the time to remove these foams or wait for that lather collapse carries out subsequent experimental later on again, this has just produced very big negative effect to the progress of testing.
At present, a lot of scholars are arranged in the research that experimentizes of the property of reduction drag to surfactant solution, but the foam production of activator solution is not controlled in the experimental provision that is adopted.Have the scholar to adopt open circuit (solution come out after no longer reflow tank) to avoid bubble-related issues in addition, but but experiment have sustainability and reuse so that carry out stably measured and data acquisition (comprising flow field survey etc.) unlike adopting closed circuit from test section.Particularly have under the situation of heating at test section, need solution after the regular hour of flowing, just can reach steady state (SS), this is that open circuit does not possess.More disadvantageous situation is when foam enters into test section, can produce very big influence to the measurement result of various parameters (flow, pressure reduction etc.), and then can make whole result that very large deviation is arranged.
Summary of the invention
At above-mentioned technological deficiency, the object of the present invention is to provide a kind of drag-reduction property experimental apparatus of surfactant solution, can reduce the foam that produces in the surfactant solution drag-reduction property experimental, accelerate the experiment progress, obtain continuous reliable experimental.

Of the present inventionly can reduce the foam that produces in the surfactant solution drag-reduction property experimental, accelerate the experiment progress, obtain continuous reliable experimental; Its concrete measure and effect are described as follows.
(1) foam falls in liquid reserve tank
From the current experiments device as can be seen, when the surfactant solution fluid was back to liquid reserve tank by test section, the solution that can directly impact in the liquid reserve tank produced a large amount of foams.And the present invention extend into drain pipe in the liquid reserve tank, and offers hole on the tube wall of its dip section.Fluid is shunted away from each hole of dip section, and rest solution can produce resistance to this fluid streams in the liquid reserve tank, thereby reduce the mainstream speed of fluid in the drain pipe, and then reduce the generation of foam.
For the small amount of foam that also can produce, by in liquid reserve tank, being provided with overflow ladle, drain pipe stretches in the overflow ladle, make reflux solution flow in the small container overflow ladle earlier, rather than directly enter in the whole solution of liquid reserve tank, the small amount of foam of generation is floated if having time, thereby guarantee do not have foam in the liquid reserve tank bottom solution once more; Simultaneously, prevented that also producing a spot of foam in the liquid reserve tank bottom is directly sucked by centrifugal ebullator, the circulation pump performance is descended, and the serviceable life that can reduce ebullator.Thereby, prevented that on the source foam from entering in the whole test loop.
(2) foam falls in test section
In the test loop design, before fluid enters into test section, to be introduced into a feed liquor chamber buffering, make the fluid that enters test section can not produce bigger fluctuation.When fluid solution flow into the feed liquor chamber from feed tube, because flow velocity is very big, impact also very greatly, and the space of feed liquor chamber can be very not big, solution also is easy to produce foam in this case.The present invention extend into the admission chamber chamber interior to feed tube, and on the tube wall of feed tube dip section, offer hole, make fluid each hole from tube wall and shunt away, thereby the mainstream speed of effluent fluid in the reduction feed tube, and reduce the impact of solution in fluid the other side feed liquor chamber bottom and the feed liquor chamber, and then reduce the generation of foam.Among the present invention also in the top design of feed liquor chamber row's foam valve, when generation foam (can not guarantee does not have foam fully) is arranged in the feed liquor chamber, can foam be removed by row of conduits the row's of opening foam valve.The function of these two measures is to have influence on the reliability of the data of surveying in order to prevent big foam group from entering into test section, and can get rid of the foam in the feed liquor chamber timely, and the pressure that prevents the feed liquor chamber is excessive and suppress bad feed liquor chamber.
Simultaneously, the present invention adopts the convergent runner at surfactant solution from the intake section that the feed liquor chamber enters into test section, rather than the sudden contraction structure; The exit portion of test section stretches into the fluid chamber, and is the flaring runner.Can prevent that like this solution from producing Maelstrom when the two-dimensional channel of turnover test section, thereby reduce the fluctuation of solution, reduce the generation probability of foam.
The present invention is used to fall the technical measures of foam, is easy to make and implement, and convenient the installation, practical; Can well be reduced in the generation rate of foam in the research of surfactant solution drag-reduction property experimental, improve the experiment progress.
