Dimensionless Keulegan Carpenter Number

Calculate the dimensionless Keulegen Carpenter number or period number.

The Keulegen Carpenter number approximates the ratio of drag forces to inertia forces acting on a structure in oscillating flow (typically wave flow).

`Kc = V T / (OOD) = V^2 / (A* OOD) `
`A* = V / T `

where :

Kc = Keulegan Carpenter number
V = velocity amplitude
T = oscillation period
OOD = structure outer diameter or characteristic length
A* = approximate acceleration amplitude

For small Keulegen Carpenter numbers inertia forces dominate. At large Keulegen Carpenter numbers drag forces dominate. The Keulegen Carpenter number can also be applied to structures oscillating in a stationary fluid.

CALCULATOR : Dimensionless Keulegan Carpenter Number Kc (General Form) [FREE]   ±

Calculate dimensionless Keulegen-Carpenter number or period number from velocity amplitude, oscillation period, and structure outer diameter.

The Keulegen-Carpenter number approximates the ratio of drag forces to inertia forces in oscillating flow (typically wave flow). It may also be appliled to objects oscillating in a stationary fluid. For small Keulegen-Carpenter numbers inertia forces dominate. At large Keulegen-Carpenter numbers drag forces dominate.

The velocity amplitude is user defined. For oscillation motion other than wave motion, enter the oscillation period as the wave period.
