摘要：

Heat transfer and flow characteristics of different viscous liquids, such as engine oil, automatic transmission fluid, 50% ethylene glycol, and deionized water, were numerically analyzed through a multi-port serpentine minichannel heat exchanger (MICHX). The heat transfer performance of engine oil was found to be poor compared to other fluids. Pressure drop in MICHX for engine oil was found to be much greater compared to water. The distribution of temperature, mass flow rate, and heat transfer rate in each channel is more even for high-viscosity fluids compared to low-viscosity fluids. The entrance region effects on thermal and flow fields for high-viscosity fluids were observed negligible.
