提出了一种新的在线混合方法来构建碳氢燃料的反应机理，避免了对转化率的过高估计，并消除了产品组成的测量误差。通过实验测量和数值模拟对在线混合动力技术进行了验证。与传统的间接接触冷却装置相比，在线冷却技术具有提高换热效率和快速消除自由基终止化学反应等优点，测量结果更加准确可靠。研究了碳氢燃料在不同压力和温度下的流动过程、传热、反应特性和热物性。由于加热段存在高温边界层，加热段的化学反应路径和产物分布与连接段不同。在此基础上，建立了包含分子化学反应和流体热物性的三维T形数学模型，验证和分析了在线混合方法的广泛适用性。对用于消除和阐明后续反应过程影响的喷射冷却剂进行了详细的性能分析，以实验和数值方法优化操作条件。随着冷却剂的增加，后续反应过程逐渐减弱，直至终止。温度和浓度的梯度是通过注入冷却剂形成的，然后由于能量和质量的传输，梯度逐渐减小到沿连接部分消失。
A novel online hybrid method is developed to construct the reaction mechanism of hydrocarbon fuel by avoiding the overestimation of conversion and removing the measurement error of product composition. The validation of online hybrid technology is conducted by experimental measurement and numerical modeling. With enhancing heat transfer efficiency and rapidly annihilating radicals to terminate chemical reaction, the measurement results of the online cooling technology are more accurate and reliable than those of the tradition indirect contact cooling apparatus. The flow process, heat transfer, reaction characteristics and thermophysical properties of hydrocarbon fuel are investigated under various pressures and temperatures. The chemical reaction pathways and product distributions at the heating section are different from those at the connecting section, due to a high-temperature boundary layer in the heating section. Further, a 3D T-shape mathematical model embedded a molecular chemical reaction and fluid thermophysical properties is established to validate and analyze the extensive availability of the online hybrid method. A detailed performance analysis of the injecting coolant that acts to eliminate and elucidate the effect of subsequent reaction process is carried out to optimize operation conditions experimentally and numerically. As the increase of the coolant, the subsequent reaction process is gradually weakened until terminated. The gradients of temperature and concentration are formed by the injection of coolant and then the gradients are gradually diminishing to disappear along the connecting part due to the energy and mass transport.
