INSFVEnergyTimeDerivative
Description
The INSFVEnergyTimeDerivative kernel implements a time derivative for the domain given by
where is the material density, is the specific heat, is the fluid temperature and the second term on the left hand side corresponds to the strong forms of other kernels.
The Jacobian is computed with automatic differentiation.
Implementation
The derivative is obtained from the definition of the fluid energy. The isobaric and isochoric heat capacities being equal for incompressible fluids,
we take the partial derivative with regards to time:
The variation of the kinetic energy is not considered in this kernel.
commentnote
The specific energy, , is currently approximated as .
