Back pressure plays an important role on performance of a R134a ejector.
- class="label">•
Primary fluid pressure has positive effects on critical back pressure.
- class="label">•
An optimal primary fluid pressure corresponds to a maximum entrainment ratio.
- class="label">•
A logarithmic relation to predict critical back pressure was presented.
