Excellent agreement of Simulations with experimental pressure drop and residence time distribution (RTD) is obtained. Streamlines, stagnant zones, Velocity profiles, and pressure fields are,obtained at different flow rates ranging from 5 to 100 mL/min. A change in the flow behavior with the presence of recirculation zones is observed with a 40 mL/min flow rate. The extent of the recirculation zones increases with increasing flow rate from 40 to 60 mL/min and is limited further by the presence of a second cylindrical post inside the heart cell, remaining almost constant in the flow rate range of 60-100 mL/min. The RTD is also determined for all flow rates, and a. comparison between different reactor designs (two-post, single-post, and low-flow-reactor-like single-post) is presented. The APR Shows a plug-flow behavior with a small degree of dispersion, which broadens the RTD. Symmetric RTD curves are obtained for the single-post designs, whereas the Gen 1 APR design experiences asymmetry in the RTD at flow rates in the range between 20 and 60 mL/min.</p>1 aNieves-Remacha, Maria, Jose1 aKukarni, Amok, A.1 aJensen, Klavs, F.  uhttps://library.ncl.res.in/content/openfoam-computational-fluid-dynamic-simulations-single-phase-flows-advanced-flow-reactor-0
