Kerosene Flow Horizontal Tube Cooling for Scramjet Ramjet Under Optimal Influence Factors
The temperature distribution of water and kerosene in the pipeline is uneven,and during the cooling process of kerosene flow in the horizontal tube of the scramjet,no further control conditions are applied for different regions,which leads to the inaccurate distribution of the velocity field in the cooling channel of kerosene flow in the horizontal tube and distortion in the analysis results of the optimal cooling factors,affecting the cooling performance of kerosene.In order to solve this problem,an optimal cooling factor analysis of kerosene flow in a horizontal tube in scramjet Ramjet is proposed.By constructing the convection heat transfer control model of the Jet fuel,the heat transfer process is divided into different stages,and the influence of inlet temperature,pressure and heat flow density on heat transfer is obtained.The heat transfer coefficients in the heating wall and between the wall and the fluid are calculated,and the boundary conditions of flow coolingin a horizontal tube are obtained.Based on this,the influencing factors on the heat transfer of supercritical Jet fuel in the horizontal tube are obtained,and the optimization cooling of kerosene flow in horizontal tubes for scramjet Ramjet are completed.The experimental results show that the fitting degree of the tube wall temperature of the proposed method is mostly consistent with the actual value,and the cooling performance is good,indicating that the proposed method has certain application value in the kerosene flow horizontal tube cooling of scramjets.
