In this study, the aeronautical and aerospace standard rocket injector have been analyzed with different aerodynamic parameters in order to understand the performance of the injectors in different atmospheric conditions. These injectors are the primary device to inject the fuel form the manifold to the ignition chamber. It creates the requited pressure, mass flow rate and the flow velocity in order to generate atomization of the fuel molecule. This atomization of the micro fuel droplet create fuel spray angle, which indeed produce high fuel burn rate. The injector with improper design may cause, unburnt fuel molecule, which will turn to carbon deposit inside the mixture chamber and gets corroded. In this paper the author has investigated the injector flow rate with respect to the injector throat area. The fuel used in this cold flow test study is commercial kerosene. The result indicates that, as the pressure at the inlet increases, the spray cone angle, mass flow rate and flow velocity also increases gradually. This numerical analysis where performed for various injector throat area with respect to various pressure rate from 20-100 psi. The best injector with all aerodynamic properties have been selected. This research paper will be benefit for the researchers and aeronautical industries, which help them to study the different aerodynamic parameter change in various injector throat area.fuel burning time to reduce the unburnt fuel and the engine is hybrid with low cost. Nowadays injector with high accuracy sensor are inbuilt with the injector head, which controls the flow with the pilot valves. Technologies are developing as the need and the demand of the product increases.

“…Since the 1960s, many scholars have studied the atomization characteristics and penetration height of fuel in crossflows in relation to engine performance (Allan and Joseph, 1971;Gad et al, 2018;Joshi and Schetz, 2015;Kolpin et al, 1968;Kush et al, 1973;Wang et al, 2014). In the early stages of this research, studies mainly focused on the influence of different factors, including the injection mode (Gad et al, 2018;Kolpin et al, 1968;Lin et al, 2004), the physical properties of the liquid (Allan and Joseph, 1971;Kush et al, 1973), and the shape of the jet hole (Joshi and Schetz, 2015;Kush et al, 1973), and a large quantity of droplet distribution data was obtained. The study of atomization characteristics in crossflows mainly focuses on the size and velocity of the droplets.…”

The atomization and mixing processes of fuel in crossflows are among the important aspects of research into rocket-based combined-cycle (RBCC) engine technology. In this paper, the droplet size and penetration height of the kerosene jet in crossflows are studied. The influences of the orifice diameter, number, and arrangement, the injection pressure drop of fuel, the orifice diameter and the Mach number of the crossflow are analyzed applying different optical measuring methods. The results reveal that the injection pressure drop of fuel and the crossflow Mach number are both positively correlated with the atomization performance, whereas the orifice diameter is negatively correlated with the atomization performance. By analyzing the penetration height under different operating conditions, it can be seen that when the other factors are kept constant, the penetration height increases with increasing orifice diameter and pressure drop. Using a least-squares, an empirical formula for the jet penetration height in terms of momentum flux ratio and axial distance was obtained.

“…It was found that the spray angle is not sensitive to the liquid flow rate for many airblast atomizers, but it can be substantially affected by supplying air pressure [37]. Gad et al [38] confirmed that the design feature of airblast atomizer (e.g., atomizing air swirler angle and atomizing air exit orifice) can also affect the spray angle as well as the droplets spatial density. While the increase of atomizing air swirler angle leads to the rise of spray angle, the spray angle reduces when atomizing air exit orifice is increasing.…”
