Description
Technical field
The present invention relates to ship drag reduction synergy field, specially a kind of submarine navigation device mucus damping device.
Background technique
In ship domain, rapidity is important always one of performance indicator.The rapidity index of ship, refers generally to ship
Under antagonism of the thrust to resistance, when making uniform rectilinear motion in hydrostatic, the speed of a ship or plane value of maximum possible can be reached.Fastly
The superiority and inferiority of speed will influence the usability and economy of ship, to the ship of war to a certain extent for ship for civil use
Speech, it is closely related with the operational performance of raising naval vessels, therefore each ship just gives explicitly quickly in design specifications
Property index.When the thrust of ship is fixed, in order to improve rapidity index, then need through various means, so that ship is navigating
The drag overall being subject to during row reduces, and resistance suffered by submarine navigation device can be divided into frictional resistance, form drag and roughness
Additional drag three parts.The optimization design that traditional drag reduction mode mainly passes through shape reduces form drag, bright and clean by improving
Surface roughness when degree and control processing reduces roughness additional drag.Used the submarine navigation device of streamline shape with
And under existing processing technology, the space that conventional method further decreases resistance is little.In fact, the frictional resistance one of ship
As be greater than form drag, 50% of drag overall or more can be accounted for.For submarine navigation device, this ratio is also higher.Therefore, think
Further decrease the resistance of submarine navigation device, it is necessary to start with from the frictional resistance for reducing surface.
The surface drag reduction method of mainstream mainly has super-hydrophobic drag reduction, groove drag reduction and mucus drag reduction etc. at present.It is wherein super thin
The air pocket structure of water drag reduction surface is easily destroyed in the presence of hydraulic pressure, is not suitable for underwater drag reduction.Groove drag reduction method
Drag reduction efficiency is relatively poor, and groove is easy to be adhered to by marine organisms and lost drag-reduction effect.The drag-reduction effect phase of mucus drag reduction
To higher.Studies have shown that a small amount of drag reduction mucus is added in a fluid, (its ingredient is mainly high molecular polymer or surface-active
Agent molecule), the frictional resistance of turbulent flow will significantly reduce.However currently, the method for mucus drag reduction is mainly used for petroleum, heating
Equal inner flow tubes road, is not yet applied to ship domain.
Traditional aircraft mucus damping device exists following insufficient: the mucus relief hole of device is provided with the end of aircraft
Place, in aircraft traveling process, is discharged mucus from mucus relief hole, to reduce resistance, still, mucus aircraft it is interior
