uniformity coefficient A coefficient related to the size distribution of a granular material, such as sand; obtained by dividing one size of grain (60% of the grains are smaller than this size, by weight) by a second size (10% of the grains are smaller than this size, by weight). ...
As these parameters cannot fully act as a basis for representing the hull curvature and its effect on the flow around the vessel there is a natural limitation on the accuracy of the approach without using more complex hull definition parameters. At the present time considerable research is ...
An experimental program was conducted to determine effects of uniformity coefficient (Cu),the curvature coefficient (Cc),the void ratio (e) and a dimensionless grain diameter defined by (d50/d100) on the discharge coefficient (Cd). Observations indicate a significant reduction of discharge ...
Flow separation and non-uniformity are the major challenges in the twin air-intakes. Twin air-intake of the single-engine aircraft provides atmospheric air to its aero-engine. The present article demonstrates the effects of single-offset and dual-offset twin air-intake and jet momentum coefficient...
The coefficient of curvature (CC) and coefficient of uniformity (CU) were calculated in order to classify the shape of the grading curve of tested blends. The CU value was in the range from 15.0 to 17.33 and CC was in the range from 0.42 to 0.64. The soil was therefore classified as ...
Conversely, it demonstrates a linear increase with the average grain size (d50), restricted grain size (d60), and the product of the coefficient of uniformity and coefficient of curvature (Cu 脳 Cc). The primary influencing factor is the type of admixture, followed by Cc and d60. Further...
