Ridge surface system for maintaining laminar flow

摘要: IN MANY APPLICATIONS WHERE FLUID FLOWS OVER A SOLID SURFACE, OR BODY MOVES THROUGH MEDIUM, LAMINAR, RATHER THAN TURBULENT SPERATED, FLOW IS DESIRABLE. FRICTION THE BOUNDARY LAYER COMBINATION WITH AN ADVERSE PRESSURE GRADIENT CAN CAUSE TURBULENCE SEPARATION EVEN ON VERY SMOOTH SURFACE. EXISTS AFT PORTION OF MOST BODIES DUE TO DECELERATION WHICH HAS BEEN ACCELERATED CONVEX FORWARD PORTION. PRESENT INVENTION CREATES PATHS RELATIVELY FAVORABLE BY PROVIDING SYSTEM RIDGES SHAPED AND LOCATED SUCH THAT THEY ACCELERATE CROSS COMPONENTS AS WELL FREE STREAM DIRECTION. SWEEP SOME OUTER INTO ENERGIZE ORDERLY FASHION. BECAUSE THINNING HAVE LESS CURVATURE THEREFORE, DECERLERATION CREATING FOR RELATIVE ACCELERATION UP RIDGES. ADDITION, MAY BE LATERAL SECTION CREATE VENTURI BETWEEN TWO IF ARE EXTENDED BEYOND TRAILING EDGE SURFACE GRADIENTS MAINTAINED EDGE. RIDGE PERFORMS FUNCTION ENERGIZING MANNER VORTEX GENERATORS WITHOUT INTRODUCING TURBULENCE. ALSO BLEED MECHANICAL COMPLEXITY.
