Volumetric Expansion

Volumetric Expansion

Volumetric Expansion

Hi all,
i need to understand how volume i increase in a chamber if i apply 10 bar pressure. Is there available a way to get this information?

Thank you

RE: Volumetric Expansion

Could you provide more details about your case ? I'm not sure if I understand what you actually mean. Do you want to analyze an increase in volume of fluid (liquid/gas) in closed tank when pressure is decreased ?

Did you consider using the basic formula below ?


where: ΔV - change in volume, V - initial volume, B - bulk modulus, Δp - change in pressure

RE: Volumetric Expansion

Maybe author want to know change of structure volume, like toy balloon.
Deformed geometry can be exported back to the spaceclaim or designmodeler.

RE: Volumetric Expansion

Thank you all.
@FEA_way i mean that i have a chamber that contains hydraulyc fluid, and i need to see how much volume i will have after 10 bar applied.
