Preliminary Design of Fuel Filling Systems Applying the Extended Bernoulli Equation on Numerical Calculation Tools 2013-36-0522
Fuel filling systems are a very important part of the entire fuel system since they are responsible for making the interaction between the user and the fuel tank, ensuring that it is properly refueled.
Guaranteeing that the system is able to refuel the tank while all the gases inside it are properly expelled, without provoking an over-pressure inside the system is very important. Designing both breathing and filling pipes of the system has a major influence on its behavior.
This work intends to calculate the minimum cross section for each pipe that allows the proper function of the system on an early stage of the development process, by applying the extended Bernoulli Equation on preliminary configuration of a fuel filling system, using numerical calculation tools as SciLab and Open Foam.
Accounting for head losses from geometries and material properties, for different flow rates and fluid properties, this method allows minimizing the overall cost of the filling system while ensuring its proper operation.
