Spray Characteristics Optimization of Biodiesel Fuel in Constant Volume Chamber Using Multi-Response Optimization Technique

This study primarily focuses on optimizing the spray characteristics of biodiesel fuel in a spray chamber. Three factors have been considered; fuel injection pressure, number of nozzle holes and fuel blends. To achieve this objective, these were chosen as the factors (injection pressure, number of nozzle holes, fuel blends). Three levels were chosen as the response variable namely, Spray penetration length (S), Spray angle (ϴ) and Sauter mean diameter (SMD). These investigaten were done with the aid of Taguchi full factorial array method.To calculate the response variables, theMulti Response Signal to Noise Ratio (MRSN) technique was used. To find optimum combination level of factors, the Taguchi's parametric design were exploited.
