Abstract
The invention relates to a high-speed flow-field water resistance testing device and relates to a water hydromechanics testing facility. The high-speed flow-field water resistance testing device comprises a water storage tank, a water inlet, a pressurizing pump, an advection limiting and pushing passage, a high-speed flow field, a jet flow passage and a drain outlet. The high-speed flow-field water resistance testing device is characterized in that water flow driven by the pressurizing pump is jetted into the jet flow passage stably linearly under limit of the advection limiting and pushing passage to form the high-speed flow field for testing of fluid water resistance. Compared with the prior art, the high-speed flow-field water resistance testing device has the advantages that control of fluid speed is easy, comparability of repeated tests is high, obtained data are reliable, and has theoretical characteristics. Accordingly, the high-speed flow-field water resistance testing device has excellent application value.
Description
One, technical field:
The present invention relates to aqueous fluid mechanical test facility, a kind of specifically High Speed Flow Field waterr rheostat test device.
Two, background technology:
In the design of facility of paddling, building course; Particularly dynamically fixing, building floating in the water body and facility; Like bridge pier, pontoon bridge, workbench etc.; MOVING STRUCTURE in the sound attitude water body reaches equipments such as submerge device, torpedo, guided missile like various warships, ship, workbench etc., all need be with the basic data of water resistance data as design and construction.The source and the collection of the water resistance data under the prior art, the test place is set many modes with case and implement in the environment place, and weighted balance is as basic foundation.The acquisition of this data and deduction, accumulation exist following deficiency and defective: though 1, the test place of case and facility have strong specific aim and targeted; But many tools are disposable, and simple property and stationarity characteristics lack repeated consistance; And cost is high; Waste is big, is difficult to satisfy under the dynamic condition the direct testing requirement under the multiple extreme condition.2, test condition is unstable, is difficult to satisfy the requirement that directly produces the theoretical property conclusion.
Three, summary of the invention:
The objective of the invention is needle to above deficiency and defective, provide a kind of fixing, stable, controlled, can repeat to drill High Speed Flow Field waterr rheostat test device examination, that can simulate multiple extreme condition.
The objective of the invention is to realize through following technical scheme:
A kind of High Speed Flow Field waterr rheostat test device; Comprise that cistern, water inlet, force (forcing) pump, advection limit force passage, High Speed Flow Field, fluidic channel and discharge opening; It is characterized in that the moving current that pour in from water inlet of force (forcing) pump body, force passage through surfacing, advection limit smooth, low-resistance, sealing up and down; The fluidic channel of the same surfacing of high fast direction, smooth, low-resistance, top opening forms the High Speed Flow Field of linear flow, releases through the discharge opening decompression.
Described High Speed Flow Field waterr rheostat test device, its fluidic channel is set to the inlet end height, the inclined-plane, straight line inclination angle that the discharge opening end is low.
Described High Speed Flow Field waterr rheostat test device, its bulk testing device is designed to annular cycling use of water.
Described High Speed Flow Field waterr rheostat test device, its water inlet is below the water surface of cistern.
