| Popis: | The present study has been attempted to systematically perform a visualizing analysis plan which can improve the flow rate, velocity and mass flow rate as a function of the size of the welding section in the injector as a key for the determination of the injection amount and time of the fuel (CH4) system for natural gas. As the setting conditions for the analysis, a minimum pressure of 2 bar and a maximum pressure of 8 bar were set to be the total pressure values in the case of the inlet, while 0 bar was set for opening drain to represent the state in the atmosphere in the case of the outlet. As a result, the characteristics with an increase in velocity could be affirmed as strong flow separation and eddy current were produced according to the model with a large size of welding section. An excellent performance with an improvement in the performance of velocity flow rate by about 40% could be affirmed in the model where the size of the welding section was designed to be 6 EA. |
