NUMERICAL SIMULATION OF LATERAL CAPILLARY TUBE-SUCTION LINE HEAT EXCHANGERS
A detailed one-dimensional numerical simulation of the thermal and fluid-dynamic behaviour of lateral capillary tube-suction line heat exchangers has been carried out. Continuity, momentum and energy equations for fluid flows, together with the energy equation in solids, are solved iteratively in a segregated manner. The numerical model allows analysis of aspect such as geometry, type of fluid, critical or non-critical flow conditions, metastable regions and transient cases.The accuracy of the detailed simulation model is demonstrated by comparing simulation results with a wide range of steady state experimental data from the technical literature. 97.7％ of the 132 data points evaluated for mass flow rate are within an error of ±15％, 81.1％ are within an error of ±10％, with a mean deviation of ±6.5％. For the suction line outlet temperature 92.8％ of the 111 data points evaluated are within an error of ±2℃ with a mean deviation of ±0.9℃.
