Thermal design and heat transfer numerical research of kerosene heat exchanger

Design of a cryogenic heat exchanger for kerosene rapid cooling is carried out, and the heat transfer mode and structural form of the heat exchanger are preliminarily designed by theoretical calculation. The corresponding physical and numerical models are established, and the cooling characteristics of aerospace kerosene were studied by numerical calculation method. By comparison with experimental data, the validity and accuracy of the numerical simulation results are verified, which provide theoretical guidance for further research.
