Fuel Tank Vibration
Application ID: 87731
This model analyses the frequency response of a fuel tank partially filled with fluid. The tank is submitted to a vertical acceleration.
Two modelling methods are considered to represent the fluid; a traditional method of smearing the mass of the fluid through the wetted surface of the fuel tank, and a multiphysics approach where the acoustic pressure within the fluid is specifically modeled.
The two methods show significant differences, highlighting how important is to accurately capture the vibroacoustic behavior when predicting stress or fatigue life on fluid filled cavities.
This model example illustrates applications of this type that would nominally be built using the following products:
however, additional products may be required to completely define and model it. Furthermore, this example may also be defined and modeled using components from the following product combinations:
The combination of COMSOL® products required to model your application depends on several factors and may include boundary conditions, material properties, physics interfaces, and part libraries. Particular functionality may be common to several products. To determine the right combination of products for your modeling needs, review the Specification Chart and make use of a free evaluation license. The COMSOL Sales and Support teams are available for answering any questions you may have regarding this.
