Collective flow is a powerful tool used to analyze the properties of a medium created during high-energy nuclear collisions. Here, we report a systematic study of the first two Fourier coefficients
$$v_1$$
and
$$v_2$$
of the proton and
$$\pi ^{+}$$
from Au+Au collisions in the energy range
$$\sqrt{s_{{\text{NN}}}}$$
= 2.11–4.9 GeV within the framework of a hadronic transport model (UrQMD). Recent results from the STAR experiment were used to test the model calculations. A mean-field mode with strong ...
