Data for: Heat Transfer Characteristic Analysis of a Novel Annular Nuclear Heat Exchanger for Propulsion System

The model in this paper is an engine model with MA<1. In order to study the air heating and flow process in the combustion chamber, the model is simplified. A one-dimensional adiabatic flow model is used to simplify the engine intake and exhaust processes. A steady one-dimensional heating model is used to simplify the combustion and heating process of the combustion chamber. At present, these simplifications accord with the general rule of flow heat transfer in engine and have been widely used in numerical simulation.本文所使用的模型为马赫数（MA）小于1的发动机模型。为研究燃烧室内部的空气加热与流动过程，本文对该模型进行了简化：采用一维绝热流动模型（one-dimensional adiabatic flow model）对发动机的进气与排气过程进行简化，采用稳态一维加热模型（steady one-dimensional heating model）简化燃烧室的燃烧与加热过程。目前，上述简化方式符合发动机内流动换热的普遍规律，已在数值模拟领域得到广泛应用。
