what does '^' mean in the 'LiftForce.C' file?

balloon · May 27, 2021, 02:27

In the LiftForce.C file, there is a code for the particle lift force:

Code:

value.Su() = mass/p.rho()*td.rhoc()*Cl*((td.Uc() - p.U())^curlUc);

As far as I know, the equation of the lift force is something like:
$F_{lift} = \rho_f \times V \times C_L \times (U_f-U_p) \times |\frac{dU_f}{dy}|$ .

So, is this "^" in the code simply means multiplication?

In the openfoam programmer guide you will find the whole list of overloaded operators and their definition

Thanks for your prompt reply. I got it from the guide, it simply means the Cross product of two vectors.
