Integral: Two cylinders with a spherical cap
Extends from TRANSFORM.Fluid.Volumes.BaseClasses.BaseDrum.DrumTypes.PartialDrumType.
Information
An integral pressurizer geometry with one spherical caps and middle and bottom cylindrical sections.
Neither the wall surface area in the bottom cylinder nor the bottom area of middle cylinder contribute to
the overall wall surface area. This is because as it currently stands, the model that uses this assumes that
there is no heat transfer at these surfaces. The surface area is therefore only the area that contributes
to heat exchange.
