Abstract: PURPOSE: An injection and intake distribution system and an injection and intake method thereof are provided to increase the stability of a structure and to reduce the fuel cost of a carrier by reducing a drag and a lift in the structure having a long shape or the carrier having the lower height than a width. CONSTITUTION: An injector(10) generates a relative injection of fluid in a certain section. An intake device(20) generates a relative intake of the fluid in the certain section. To prevent the vertical perturbation by the falling of rear pressure in the rear stream of the fluid, the injectors and the intake devices are alternatively arranged lengthwise on the surface of an object(10).

Abstract: PURPOSE: A drag reducing device of a carrier with a variable separation point and a method thereof are provided to reduce fuel consumption and increase moving speed by actively decreasing drag force of the small or large carrier with the variable separation point. CONSTITUTION: A drag reducing device is used for a carrier(1) having the spherical or oval surface with the variable separation point. A slit(2) is formed in the surface of the carrier, and placed within the range of 50 to 80 angular degrees from the stagnation point. A boundary disturbance unit(3) is formed in the drag reducing device to periodically inject and suck fluid such as water or air through the slit, and composed of an oscillation part having a diaphragm formed close to the slit, an electromagnet actuator connected to the diaphragm by a supporter to vibrate the diaphragm by an electromagnet and a control unit applying a control signal to the electromagnet actuator to control vibration frequency of the diaphragm.

Abstract: PURPOSE: A micro channel structure for saving a driving energy is provided to reduce a pressure loss at a connection channel section, which connects linear channel sections to each other, by forming a width of the connection channel section larger than a width of the linear channel sections. CONSTITUTION: A micro channel structure(1) includes a micro channel having a micro-sized width. The micro channel has a plurality of linear channel sections(10), which linearly extend, and connection channel sections(20,30) for connecting the linear channel sections(10) to each other. A width of the connection channel sections(20,30) becomes enlarged from one linear channel section(10) to the other linear channel section(10). That is, the width of the connection channel sections(20,30) is maximized at a center of the connection channel sections(20,30) and becomes reduced as the connection channel sections(20,30) reach the other linear channel section(10).

Abstract: 본 발명은 연결채널부를 통과하며 발생하는 압력강하를 줄일 수 있는 형상을 갖는 마이크로채널 구조체에 관한 것이다. 본 발명에 따른 마이크로채널 구조체는 마이크로미터 단위의 미세한 폭을 가지는 액체유동용 마이크로채널들이 형성되어 있으며, 그 마이크로채널은 직선형으로 연장되는 다수의 직선채널부와, 인접된 한 쌍의 직선채널부들을 연결하는 연결채널부를 구비하는 데, 상기 연결채널부가 그 연결채널부에 의해 연결되는 직선채널부들의 폭보다 큰 폭을 가지도록 형성되어 있는 것에 그 특징이 있다. 이러한 본 발명에 따른 마이크로채널 구조체를 이용하면, 유체가 연결채널부를 통과하며 발생하는 압력강하를 줄임으로써 유체를 구동하는 데에 필요한 에너지를 절감할 수 있을 뿐만 아니라, 이로 인하여 펌프 및 주변장치 등을 포함한 마이크로 유체 장치를 소형화하는 것이 가능하다는 효과를 얻을 수 있다.
