A method to estimate the planar, instantaneous body force distribution from velocity field measurements

Albrecht, T.; Weier, T.; Gerbeth, G.; Metzkes, H.; Stiller, J.

We present a simple method to derive a planar, instantaneous body force distribution from a given 2-D velocity field without knowledge of the pressure field. If the body force consists of one component only, spatial integration completely recovers this component.
Particle Image Velocimetry and Direct Numerical Simulations of a wall jet induced by a known body force were conducted to validate the method, demonstrating a good agreement of the original and reconstructed force fields.
