TEMA Shell Entrance Area Calc with Impingement Plate
TEMA Shell Entrance Area Calc with Impingement Plate
(OP)
Does anyone know how the TEMA shell entrance area calc (RGP-RCB-4.621, 4.622) is done when the impingement plate is located inside of the inlet nozzle (i.e. a circular disc supported by cross-braces in the nozzle I.D. just outside of the shell I.D.)?? This arrangement is not represented in the diagrams. Would you assume that there is no impingement plate?

I generally consider this a poor design because of the high localized velocities (vibration potential) and poor use of pressure drop.

For lack of any method of calculation, you could calculated the area around the plate and then calculate from this an equivalent nozzle diameter to use in the TEMA equation.
