parameter in reactor design, which has not been well assessed in publications to date. To
rectify this deficit and evaluate the bypass flow fraction in a VHTR core, experiments were
conducted using a small-scale model for a portion of a prismatic core of VHTR with air as the
working fluid. Bypass flow simulations were performed using STAR-CCM+ software to
validate the code by comparing basic physical quantities related to bypass flow to each …
