Eulerian derivation of the conservation equation for energy in a non-inertial frame of reference in arbitrary motion

作者:

Highlights:

• Arbitrary motion considered here as unsteady combined translation and rotation.

• Eulerian method to transform vectors and scalars to non-inertial frame is presented.

• Total energy equation is transformed from inertial frame to non-inertial frame.

• Five fictitious work terms dependent on the type of motion are obtained.

• Seven types of motion are considered to determine fictitious work terms to include.
