Keyword Flow resistance Optimization Pressure distribution Flow system Flow system Pressure distribution Optimization Flow resistance Abstract In the heat flow analysis, optimizing the flow systems often requires researchers to take a long time to simulate and test. The purpose of this study is to propose a new way to reduce the time in optimizing flow systems. We use the numerical simulation software to obtain optimized flow systems' pressure distributions to discuss the feasibility of this method. Several different flow systems with variable channel diameter ratio (D2/D1), fixed flow volumes and the total pressure difference are studied to find out the regularity between the optimized flow systems and pressure distributions. Also, to understand whether we can use pressure distributions to determine a flow channel is optimized or not. The results showed that the best pressure distribution will close to the ideal line. This ideal line is defined by connecting the inlet pressure and the outlet pressure in the pressure-distance plot. The best configuration will provide the highest volumetric flow rate, that is, the best flow performance. Advisor Committee Kuan-Min Wang - advisor
