<P>PROBLEM TO BE SOLVED: To provide a surface structure which is effective in terms of efficiency, economics, manufacturing and maintenance and suitable for the use in a ship, a boat, a pipe used for hydroelectric power generation or the like at a low and mid speed, or a surface structure which is suitable for an airliner of mid speed. <P>SOLUTION: A structure constituted on the surface of an object is used for reducing the resistance to a medium surrounding the object, and a plurality of recesses (surface structures 1, 20, 40, and 60) is formed on the structure. The recesses on the surface are not penetrated and have disruption edges (5, 25, 44, and 66) which are placed in proximity to a hole. The disruption edge positioned in the upper stream of the recess changes a flowing medium which is in the closest vicinity to the surface to a turbulent flow when a flowing medium passes through the disruption edge. Then the depth of the recess is at least about 2 mm when measured from the surface. <P>COPYRIGHT: (C)2008,JPO&INPIT | ||||||

PROBLEM TO BE SOLVED: To expand an application range of a Karman's vortex reducing body and to enhance a degree of freedom at an application portion by providing the reducing body freely attachable/detachable to/from a surface of an object in contact with fluid and made of a base material provided with many projecting parts, recessed parts, projecting lines or recessed grooves on a surface. SOLUTION: In this Karman's vortex reducing body 1, a synthetic resin sheet 10 is made as a base material, a semi-spherical synthetic resin projecting part 2 is molded integrally with the surface, and an adhesive layer 11 and a peeling sheet 12 are adhered to a rear face of the sheet 10. When the body 1 is used, the reducing body 1 is cut according to an adhering object portion, and the peeling sheet 12 is peeled and adhered to a surface of an automobile.

PROBLEM TO BE SOLVED: To reduce turbulence drag by regularly or irregularly providing multiple projections or recesses having a prescribed shape and introducing a disturbance promoting or suppressing the occurrence of a roll pair on a wall face at a prescribed pitch. SOLUTION: Multiple V-shaped lugs 55 each having an apex facing an arrow 53 are regularly or irregularly displacedly arranged on the surface 51 of a wall 52 kept in contact with the flow field of a fluid in this turbulence control device 50. The apex angle of each lug 55 is set to 50-90°, its height is set to 5-15 wall units, the pitch of lines is set to 100-300 wall units, the pitch of the flow direction is set to 200-400 wall units, and the size of the flow direction is set to 150-250 wall units, where the wall unit is the value divided with viscosity by the square root of the product of density and stress. The V-shaped lug 55 is provided with a recessed or protruded curve from the apex, or recesses may be arranged in the surface 51 in place of the lugs 55. Turbulence can be easily controlled, and drag can be sharply reduced. COPYRIGHT: (C)1998,JPO | ||||||

PURPOSE: To control turbulence through compensation of a starting mode by connecting obliquely propagating structures so as to increase/decrease the interaction between a system of roll pairs and a propagation structure and locally guiding two separate disturbances to a turbulent wall region. CONSTITUTION: Obliquely propagating structures are connected so as to increase/ decrease the interaction of propagation structures with a system of roll pairs thereby locally increasing/decreasing the disturbance drag in a flow region. For forming a composite disturbance region compensating the structure, two simultaneously operating means are provided to produce two effective, separate disturbances in a local region. In this embodiment, the apparatus 50 comprises strip-shaped means 51 of delta-shaped projections 53 and a resonator box-shaped means 54 formed of a sound generator 55 having a loudspeaker 56 attached to its free end 58. This arrangement can produce the disturbances generating a pair of oblique waves enhancing the turbulence so as to organize the turbulence for reducing the disturbance drag.

PURPOSE: To decrease a drag by increasing the flow rate of turbulence. CONSTITUTION: Turbulence in a wall-bounded fluid flow field 10 having a turbulent wall region is characterized by a system of roll pairs 14, 16 extending in the direction of flow 13, and propagating structures interacting with the system of roll pairs. The turbulence is controlled by introducing into the turbulent flow a disturbance that changes the character of the propagating structures directed at a predetermined inclined angle to the direction of flow. Where the disturbance increases the amplitudes of the propagating structure, turbulent mixing or heating is increased; when the disturbance decreases the amplitude of the propagating structure, the turbulent drag is decreased.

PURPOSE: To reduce a drag relating to a surface by forming a pattern irradiating the surface of an article with a laser beam. CONSTITUTION: A mask 14 is irradiated through a beam operation optical device 12 and next a target 18 is irradiated through an image lens system 16 with a ultraviolet laser beam pulse in an excimer laser 10. A beam profile incident on the mask 14 is utilized by the beam processing optical device 12. A pattern of the ultraviolet laser beam incident on the target 18 is demarkated by the mask 14. Since the mask 14 is correctly imaged on the surface of the target in many systems, it is required to provide a positional sensor. | ||||||

PURPOSE: To provide soft and extendible/contractible substrate suitable for swimming suits, etc., by installing a section of film having a patterned surface to reduce drag resistance when fluid flows on the substrate at a front edge, and overlapping a back edge of an adjacent section with the front edge to arrange them in a cascade form. CONSTITUTION: Patterns 14, that is parallel ridges and troughs, for example, are formed on a surface of film of polyolefine or the like to reduce drag resistance of flowing water, and it is cut into oval sections 12. This section 12 is bound to a soft and/or extendible/contractible substrate 11 at a front edge by binding agent 13 to be installed in such a way that its back edge is overlapped with a front edge of the next section 12 to form a cascade arrangement. As this binding agent 13, pressure-sensitive binding agent of polyacrylate or the like is used. This can thus be applied as the soft and/or extendible/ contractible substrate for swimming suits, etc. COPYRIGHT: (C)1990,JPO | ||||||
