Lingnan Lin (Assoc)
Dr. Lingnan Lin is a research scientist in the HVAC&R Equipment Performance Group of the Building Energy and Environment Division of the Engineering Laboratory (EL). He was a postdoctoral research associate (2018–2021) and a visiting graduate student (2016–2018) in the same group at NIST.
Dr. Lin’s main research interest is in the measurement and modeling of single- and two-phase fluid flow and heat transfer. He developed a novel approach and a new neural network (DimNet) to generate explicit, algebraic correlations for complex thermal-hydraulic problems. He established a universal model using DimNet to predict the flow boiling heat transfer coefficient in microfin tubes. He has been a key contributor to the NIST long-term project to measure the two-phase heat transfer and pressure drop characteristics of refrigerants with low global warming potential (GWP). He also participates in a new project that aims to build a test facility for characterizing the pressure losses of pipe fittings and to establish a new standard method of test.
In addition to his research in fluid flow and heat transfer, Dr. Lin has conducted extensive work on nanolubricants for enhanced heat transfer. He also used molecular dynamics simulation to study the thermophysical properties and rheological behavior of polyol ester lubricants. Currently, he is studying direct-contact heat-exchangers (DCHX) with phase change material (PCM) for thermal energy storage (TES). In 2021 and 2022, he was awarded two NIST-EL Exploratory Project grants for the DCHX-TES research.
Dr. Lin received the NIST-EL Distinguished Associate Award for “advancing the measurement and modeling sciences of heat transfer and thermophysical properties of low-GWP refrigerants and energy materials.” He is a member of the American Society of Mechanical Engineers (ASME). He was selected into the 2022-2023 ASME ECLIPSE Program, a competitive leadership development program for early career engineers around the world. He is also a Junior Member of the International Institute of Refrigeration (IIR) Commission B1.
