Flat plate skin friction coefficient
WebMar 11, 2024 · In the case of unseparated laminar flow on a flat plate (\(Re\lesssim {10}^{6}\)), skin friction is proportional to U 3/2 1. Quantifying these types of friction is of critical importance for the ... WebThe Turbulent flat-plate skin-friction coefficient formula is defined as the ratio of constant (0.0592) to the local Reynolds number raise to power 0.2 and is represented as cf = 0.0592/ (Rel)^0.2 or Skin friction coefficient = 0.0592/ (Local Reynolds Number)^0.2. Local Reynolds Number is the ratio of inertial forces to viscous forces.

Skin friction drag is a type of aerodynamic or hydrodynamic drag, which is resistant force exerted on an object moving in a fluid. Skin friction drag is caused by the viscosity of fluids and is developed from laminar drag to turbulent drag as a fluid moves on the surface of an object. Skin friction drag is generally expressed in terms of the Reynolds number, which is the ratio between inertial force and viscous force. WebJan 6, 2011 · Turbulent Flat Plate: Study #2 Introduction .
