    This paper reports results for directed flow \(v_{1}\) and elliptic flow \(v_{2}\) of charged particles in Cu+Cu collisions at \(\sqrt{s_{NN}}=\) 22.4 GeV at the Relativistic Heavy Ion Collider. The measurements are for the 0-60% most central collisions, using charged particles observed in the STAR detector. Our measurements extend to 22.4 GeV Cu+Cu collisions the prior observation that \(v_1\) is independent of the system size at 62.4 and 200 GeV, and also extend the scaling of \(v_1\) with \(\eta/y_{\rm beam}\) to this system. The measured \(v_2(p_T)\) in Cu+Cu collisions is similar for \(\sqrt{s_{NN}} = 22.4-200\) GeV. We also report a comparison with results from transport model (UrQMD and AMPT) calculations. The model results do not agree quantitatively with the measured \(v_1(\eta), v_2(p_T)\) and \(v_2(\eta)\).
