The multiphase flow was studied using the two-fluids Eulerian Received in revised form 16 March 2017 model. A constant boiling rate was assumed over the U-tubes walls and a blending model was applied Accepted 17 March 2017 for solving the interface momentum exchange. Steady-state conditions were simulated both by CFD Available online 30 March 2017 and by a system code (RELAP) with the aim to compare the recirculation flow rate, the flow through each one of the two riser legs and the five by-passes connecting the legs, the void distribution, the phase veloc- Keywords:
