Total Energy At Nozzle Exit For a Rotary Engine Calculator

Rotary engines, often referred to as Wankel engines, are a type of internal combustion engine known for their unique rotor-based design. Unlike traditional piston engines, rotary engines have a rotating triangular rotor that completes three strokes (intake, compression, and exhaust) during one revolution. The exit of the exhaust gases in a rotary engine is not associated with a conventional nozzle, but we can still discuss the total energy at the exit.

The total energy ($E$) at the nozzle exit can be expressed as:

where,

• E is the Total Energy, i.e sum of kinetic and potential energy
• $h$ is the static enthalpy at the nozzle exit,
• $V$ is the velocity of the exhaust gases relative to the reference frame of the exhaust gases
