Abstract: In this paper, based on the heart‐shaped microreactors (Advanced Flow Reactor, AFR), the asymmetric heart‐shaped passive microreactor is designed. The length ratio (Ratio = L0/L) is defined as a measure of asymmetry. L0 is the length of the baffle in the minor sub‐channel, and L is the length of the baffle in the major sub‐channel. The total length of the baffle is Lt (Lt = L0 + L). For unchanged Lt, the mixing index obtained from the asymmetric heart‐shaped passive microreactor under the conditions of Ratio = 0.767 and Re = 100 is 53.86 %, which is 9.44 % higher. For changed Lt, at Re = 6, the mixing is dominated by diffusion mixing, and the standard error of the mixing index among heart‐shaped passive microreactors with different Ratio is within 0.05 %; at Re = 60, the mixing is dominated by convective mixing. The mixing index of asymmetric heart‐shaped passive microreactor with Ratio = 0.8 can reach 0.4386, which is 2.6 % higher; at Re = 100, the mixing index increases by 2.86 %.
