As an adjective rotodynamic is

(of a pump) in which energy is continuously imparted to the pumped fluid by means of a rotating impeller, propeller, or rotor (unlike a positive displacement pump, in which a fluid is moved by trapping a fixed amount of fluid and forcing the trapped volume into the pump's discharge).

As adjectives the difference between fluid and rotodynamic

is that fluid is of or relating to fluid while rotodynamic is in which energy is continuously imparted to the pumped fluid by means of a rotating impeller, propeller, or rotor (unlike a positive displacement pump, in which a fluid is moved by trapping a fixed amount of fluid and forcing the trapped volume into the pump's discharge).

As a noun fluid

is any substance which can flow with relative ease, tends to assume the shape of its container, and obeys Bernoulli's principle; a liquid, gas or plasma.

As a noun energy

is the impetus behind all motion and all activity.
