Journal of Thermal Science 2016年第6期25卷 581-588页

作者： P.Raghu N.Nallusamy Sri Venkateswara College of Engineering Department of Mechanical Engineering SSN College of Engineering Department of Mechanical Engineering

This study discusses about the optimization of spray characteristics of biodiesel fuel in a spray *** factors namely,fuel injection pressure,fuel temperature and fuel blends were chosen as the influencing factor for the set *** levels were chosen in each factor and spray tip penetration,spray cone angle and Sauter mean diameter(SMD) were taken as the response *** were designed by employing design of experiments method and Taguchi full factorial array was used to conduct the tests with different levels of the chosen *** Response Signal to Noise ratio(MRSN) was calculated for the response variables and the optimum combination level of factors was obtained simultaneously using Taguchi's parametric *** experiments were conducted for the obtained optimum combination level of factors and the results were compared with the normal operating conditions and significant improvement were observed in the response variables.

Besides safety and low-cost,the start/shutdown/restarting and throttling ability are the other two significant advantages of hy-brid rocket motors(HRMs) compared with liquid and solid *** this study,a two-stage variable thrust and non-toxic 98%HP/HTPB hybrid rocket motor(VTHRM) is designed and applied in a sounding rocket,and the design parameters of the motor are analyzed and optimized.A computational program is developed to design the motor system structure,to predict the interior ballistics and the ballistic trajectory.A star grain and a wheel grain are *** design of experiment(DOE),variance analysis and the main effect analysis are employed to investigate the influence of the main design parameters on mo-tor *** multidiscipline feasible(MDF) approach is applied to establish the optimization procedure after analyz-ing the system design structure matrix.A modified differential evolution algorithm is employed to maximize the load *** results indicate that the wheel grain could obtain a larger load mass and a lower length to diameter ratio,and that throttling markedly meliorates the motor and rocket *** conclusions drawn from the analysis and optimization could pro-vide instructive guide and theoretical basis for engineering designs.
