The Characteristic of Friction-Factor on Honeycomb Surfaces (Part I : Experimantal Tests and Friction-Factor Modeling)

허니콤 표면의 마찰계수 특성에 관한 연구 (Part 1 : 표면 마찰계수 측정 및 모델링)

Friction-factors for honeycomb surfaces are measured with a flat plate tester. The flat plate test apparatus is described and method is discussed for determining the friction-factor experimentally. The friction-factor is calculated for the flat plate test based on the Fanno-line flow. The test parameters are honeycomb cell width, depth, clearance, inlet pressure, and Reynolds number(or Mach number). A new empirical friction-factor model for honeycomb surfaces are developed as a function of these parameters.
